How to Write a Research Paper Introduction (with Examples)

The research paper introduction section, along with the Title and Abstract, can be considered the face of any research paper. The following article is intended to guide you in organizing and writing the research paper introduction for a quality academic article or dissertation.

The research paper introduction aims to present the topic to the reader. A study will only be accepted for publishing if you can ascertain that the available literature cannot answer your research question. So it is important to ensure that you have read important studies on that particular topic, especially those within the last five to ten years, and that they are properly referenced in this section. 1 What should be included in the research paper introduction is decided by what you want to tell readers about the reason behind the research and how you plan to fill the knowledge gap. The best research paper introduction provides a systemic review of existing work and demonstrates additional work that needs to be done. It needs to be brief, captivating, and well-referenced; a well-drafted research paper introduction will help the researcher win half the battle.

The introduction for a research paper is where you set up your topic and approach for the reader. It has several key goals:

• Present your research topic
• Capture reader interest
• Summarize existing research
• Position your own approach
• Define your specific research problem and problem statement
• Highlight the novelty and contributions of the study
• Give an overview of the paper’s structure

The research paper introduction can vary in size and structure depending on whether your paper presents the results of original empirical research or is a review paper. Some research paper introduction examples are only half a page while others are a few pages long. In many cases, the introduction will be shorter than all of the other sections of your paper; its length depends on the size of your paper as a whole.

The introduction in a research paper is placed at the beginning to guide the reader from a broad subject area to the specific topic that your research addresses. They present the following information to the reader

• Scope: The topic covered in the research paper
• Context: Background of your topic
• Importance: Why your research matters in that particular area of research and the industry problem that can be targeted

The research paper introduction conveys a lot of information and can be considered an essential roadmap for the rest of your paper. A good introduction for a research paper is important for the following reasons:

• It stimulates your reader’s interest: A good introduction section can make your readers want to read your paper by capturing their interest. It informs the reader what they are going to learn and helps determine if the topic is of interest to them.
• It helps the reader understand the research background: Without a clear introduction, your readers may feel confused and even struggle when reading your paper. A good research paper introduction will prepare them for the in-depth research to come. It provides you the opportunity to engage with the readers and demonstrate your knowledge and authority on the specific topic.
• It explains why your research paper is worth reading: Your introduction can convey a lot of information to your readers. It introduces the topic, why the topic is important, and how you plan to proceed with your research.
• It helps guide the reader through the rest of the paper: The research paper introduction gives the reader a sense of the nature of the information that will support your arguments and the general organization of the paragraphs that will follow. It offers an overview of what to expect when reading the main body of your paper.

What are the parts of introduction in the research?

A good research paper introduction section should comprise three main elements: 2

• What is known: This sets the stage for your research. It informs the readers of what is known on the subject.
• What is lacking: This is aimed at justifying the reason for carrying out your research. This could involve investigating a new concept or method or building upon previous research.
• What you aim to do: This part briefly states the objectives of your research and its major contributions. Your detailed hypothesis will also form a part of this section.

How to write a research paper introduction?

The first step in writing the research paper introduction is to inform the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening statement. The second step involves establishing the kinds of research that have been done and ending with limitations or gaps in the research that you intend to address. Finally, the research paper introduction clarifies how your own research fits in and what problem it addresses. If your research involved testing hypotheses, these should be stated along with your research question. The hypothesis should be presented in the past tense since it will have been tested by the time you are writing the research paper introduction.

The following key points, with examples, can guide you when writing the research paper introduction section:

• Highlight the importance of the research field or topic
• Describe the background of the topic
• Present an overview of current research on the topic

Example: The inclusion of experiential and competency-based learning has benefitted electronics engineering education. Industry partnerships provide an excellent alternative for students wanting to engage in solving real-world challenges. Industry-academia participation has grown in recent years due to the need for skilled engineers with practical training and specialized expertise. However, from the educational perspective, many activities are needed to incorporate sustainable development goals into the university curricula and consolidate learning innovation in universities.

• Reveal a gap in existing research or oppose an existing assumption
• Formulate the research question

Example: There have been plausible efforts to integrate educational activities in higher education electronics engineering programs. However, very few studies have considered using educational research methods for performance evaluation of competency-based higher engineering education, with a focus on technical and or transversal skills. To remedy the current need for evaluating competencies in STEM fields and providing sustainable development goals in engineering education, in this study, a comparison was drawn between study groups without and with industry partners.

• State the purpose of your study
• Highlight the key characteristics of your study
• Describe important results
• Highlight the novelty of the study.
• Offer a brief overview of the structure of the paper.

Example: The study evaluates the main competency needed in the applied electronics course, which is a fundamental core subject for many electronics engineering undergraduate programs. We compared two groups, without and with an industrial partner, that offered real-world projects to solve during the semester. This comparison can help determine significant differences in both groups in terms of developing subject competency and achieving sustainable development goals.

The purpose of the research paper introduction is to introduce the reader to the problem definition, justify the need for the study, and describe the main theme of the study. The aim is to gain the reader’s attention by providing them with necessary background information and establishing the main purpose and direction of the research.

The length of the research paper introduction can vary across journals and disciplines. While there are no strict word limits for writing the research paper introduction, an ideal length would be one page, with a maximum of 400 words over 1-4 paragraphs. Generally, it is one of the shorter sections of the paper as the reader is assumed to have at least a reasonable knowledge about the topic. 2 For example, for a study evaluating the role of building design in ensuring fire safety, there is no need to discuss definitions and nature of fire in the introduction; you could start by commenting upon the existing practices for fire safety and how your study will add to the existing knowledge and practice.

When deciding what to include in the research paper introduction, the rest of the paper should also be considered. The aim is to introduce the reader smoothly to the topic and facilitate an easy read without much dependency on external sources. 3 Below is a list of elements you can include to prepare a research paper introduction outline and follow it when you are writing the research paper introduction. Topic introduction: This can include key definitions and a brief history of the topic. Research context and background: Offer the readers some general information and then narrow it down to specific aspects. Details of the research you conducted: A brief literature review can be included to support your arguments or line of thought. Rationale for the study: This establishes the relevance of your study and establishes its importance. Importance of your research: The main contributions are highlighted to help establish the novelty of your study Research hypothesis: Introduce your research question and propose an expected outcome. Organization of the paper: Include a short paragraph of 3-4 sentences that highlights your plan for the entire paper

Cite only works that are most relevant to your topic; as a general rule, you can include one to three. Note that readers want to see evidence of original thinking. So it is better to avoid using too many references as it does not leave much room for your personal standpoint to shine through. Citations in your research paper introduction support the key points, and the number of citations depend on the subject matter and the point discussed. If the research paper introduction is too long or overflowing with citations, it is better to cite a few review articles rather than the individual articles summarized in the review. A good point to remember when citing research papers in the introduction section is to include at least one-third of the references in the introduction.

The literature review plays a significant role in the research paper introduction section. A good literature review accomplishes the following: Introduces the topic – Establishes the study’s significance – Provides an overview of the relevant literature – Provides context for the study using literature – Identifies knowledge gaps However, remember to avoid making the following mistakes when writing a research paper introduction: Do not use studies from the literature review to aggressively support your research Avoid direct quoting Do not allow literature review to be the focus of this section. Instead, the literature review should only aid in setting a foundation for the manuscript.

Remember the following key points for writing a good research paper introduction: 4

• Avoid stuffing too much general information: Avoid including what an average reader would know and include only that information related to the problem being addressed in the research paper introduction. For example, when describing a comparative study of non-traditional methods for mechanical design optimization, information related to the traditional methods and differences between traditional and non-traditional methods would not be relevant. In this case, the introduction for the research paper should begin with the state-of-the-art non-traditional methods and methods to evaluate the efficiency of newly developed algorithms.
• Avoid packing too many references: Cite only the required works in your research paper introduction. The other works can be included in the discussion section to strengthen your findings.
• Avoid extensive criticism of previous studies: Avoid being overly critical of earlier studies while setting the rationale for your study. A better place for this would be the Discussion section, where you can highlight the advantages of your method.
• Avoid describing conclusions of the study: When writing a research paper introduction remember not to include the findings of your study. The aim is to let the readers know what question is being answered. The actual answer should only be given in the Results and Discussion section.

To summarize, the research paper introduction section should be brief yet informative. It should convince the reader the need to conduct the study and motivate him to read further.

Welcome to our comprehensive guide on crafting the perfect introduction for your research paper. In this blog, we’ll explore the crucial elements of a strong introduction, highlight common pitfalls to avoid, and provide practical tips to effectively set the stage for your study’s objectives and significance. 

Table of Contents

Lack of a clear thesis statement, lack of clear objectives and scope, failure to establish the research significance, insufficient background information, inadequate literature review, ignoring the research gap, overly technical language, poor organization and flow, neglecting the audience, the importance of a good introduction.

A strong introduction sets the tone for the entire paper, guiding the reader through the research journey. It provides context, establishes relevance, and ensures the reader understands the importance of the study.

Starting a research project is exciting, but getting the introduction right is key. It’s like opening the door to your study and inviting readers in. However, there are some common missteps that can trip you up along the way.

Common mistakes to avoid.

A thesis statement is the central argument or claim that guides the entire research paper. It is a concise summary of the main point or claim of the paper and is typically found at the end of the introduction. A clear thesis statement helps to focus the research, provide direction, and inform the reader of the paper’s purpose. Expert reviewers may even skip the rest of the introduction (as they are well versed in the topic) and focus only on your thesis statement, so it’s vital to make sure it is perfect!

When a research introduction lacks a clear thesis statement, several issues can arise:

• Ambiguity : Without a clear thesis, the reader may be confused about the paper’s purpose and the main argument. Do not talk in vague terms. Whenever possible, use terminology established in recent literature. Narrow down the key aspects of the association that you are investigating (the study sample, the outcome and predictor measures) as much as possible.
• Lack of Focus : The paper can become unfocused and meander through unrelated topics, making it difficult for the reader to follow the argument. Do not try to have more than 1-2 main aims in a paper. Even if you have done supplementary analysis, it is better to say so in the discussion. As a rule of thumb, try to answer one major question only!
• Weak Argumentation : A well-defined thesis provides a strong foundation for building arguments. Without it, the arguments may appear weak and unsupported.

Let's be more practical:

1- In this paper, I will discuss climate change.

• Problem: This statement is too broad and vague. It does not provide a clear direction or specific argument.

2- This paper argues that climate change, measured by global average temperature change, is primarily driven by human activities, such as deforestation and the burning of fossil fuels, and proposes policy measures to mitigate its impact.(1)

• Strengths: – Specificity : It clearly states that the paper will focus on human activities as the main drivers of climate change. – Argument : It presents a specific claim that the paper will argue. – Direction : It hints at the structure of the paper by mentioning policy measures.

Powerful Tips:

• Be Specific : Clearly define the main argument or claim. Avoid vague or broad statements.
• Be Concise : Keep the thesis statement concise, ideally one to two sentences.
• Provide Direction : Indicate the structure of the paper by hinting at the main points that will be discussed.
• Revise as Needed : Be prepared to revise the thesis statement as your research progresses and your understanding deepens.

Transform research ideas into published papers!

A clear statement of objectives and scope is crucial in a research paper introduction because it outlines what the study aims to achieve and defines the boundaries within which the research will be conducted.

Example of Lacking Clear Objectives and Scope: This paper examines the impacts of climate change on agriculture.

• Problem : This statement is too broad and vague. It does not specify what aspects of climate change or agriculture will be studied, nor does it define the geographical or temporal scope.

Example with Clear Objectives and Scope: This study aims to investigate the effects of rising temperatures and changing precipitation patterns on crop yields in the Midwest United States from 2000 to 2010. The objectives are to (1) assess the impact of temperature changes on corn and soybean yields, (2) analyze how variations in precipitation affect crop growth, and (3) identify adaptive strategies employed by farmers in the region.(2)

Powerful tips:

• Be Specific : Clearly state what the study aims to achieve and avoid vague or broad statements.
• Identify Key Areas : Outline the main areas or aspects that the research will focus on.
• Set Boundaries : Define the geographical, temporal, and conceptual boundaries of the research.
• List Objectives : Clearly articulate specific research objectives or questions that the study will address.
• Stay Realistic : Ensure that the objectives and scope are achievable within the constraints of the research project.
• Make it flow : Make sure you are not repeating the same concepts as the thesis statement, as these two sections are often presented back-to-back in the final paragraph of the introduction! Remember: the thesis statement is your hypothesis or question, and your objectives are ‘how’ you are going to test your thesis.

This mistake can result in the research appearing trivial or irrelevant, diminishing its potential impact. When the significance of the research is not well-established, readers may struggle to understand the value of the study and why they should care about it.

Example of Failure to Establish Research Significance: This study investigates the effects of social media usage on sleep patterns among teenagers.

• Problem : The significance of studying social media’s impact on sleep patterns is not explained. The reader may wonder why this research is important or what implications it has.

Example with Established Research Significance: This study investigates the effects of social media usage on sleep patterns among teenagers. Understanding this relationship is crucial because insufficient sleep is linked to numerous health issues, including decreased academic performance, heightened stress levels, and increased risk of mental health problems. With the pervasive use of social media among adolescents, identifying how it impacts sleep can inform strategies for promoting healthier habits and improving overall well-being in this vulnerable age group.(3)

• Link to Broader Issues : Connect the research topic to broader issues or trends that highlight its relevance and importance.
• Explain Practical Implications : Discuss the potential practical applications or benefits of the research findings.
• Address Gaps in Knowledge : Identify gaps in the existing literature that the research aims to fill.
• Highlight Potential Impact : Emphasize the potential impact of the research on the field, society, or specific populations.
• Use Concrete Examples : Provide concrete examples or scenarios to illustrate the significance of the research.

Feeling swamped by the complexities of Systematic Reviews?

Insufficient background information in the introduction of a research paper refers to failing to provide enough context for the reader to understand the research problem and its significance. Background information sets the stage for the research by offering necessary details about the topic, relevant theories, previous studies, and key terms.

This may lead to:

• Reader Confusion : Without adequate context, readers may struggle to understand the research question, its importance, and how it fits into the broader field of study.
• Weak Justification : Insufficient background can undermine the rationale for the research, making it difficult to justify why the study is necessary or valuable.
• Misinterpretation : Lack of context can lead to misinterpretation of the research objectives, methods, and findings.

Example of Insufficient Background Information: In recent years, many researchers have studied the effects of social media on teenagers. This paper explores the relationship between social media use and anxiety among teenagers.

• Problem : This introduction lacks specific details about the previous research, the theoretical framework, and key terms. It does not provide enough context for the reader to understand why the study is important.

Example of Adequate Background Information: Social media platforms have become an integral part of teenagers’ daily lives, with studies showing that 95% of teens have access to a smartphone and 45% are online almost constantly. Previous research has linked excessive social media use to various mental health issues, including anxiety and depression. However, the mechanisms underlying this relationship remain unclear. This paper explores the impact of social media use on anxiety levels among teenagers, focusing on the roles of social comparison and cyberbullying.(4)

• Review Relevant Literature : Summarize key studies and theories related to your topic.
• Provide Context : Explain the broader context of your research problem.
• Define Key Terms : Ensure that any specialized terms or concepts are clearly defined.
• Identify the Research Gap : Highlight what is not yet known or understood about your topic.
• Be Concise : Provide enough information to set the stage without overwhelming the reader with details.

Getting No Replies from Institutions? Don't Stress!

This mistake can occur when the literature review is too brief, lacks depth, omits key studies, or fails to critically analyze previous work. An inadequate literature review can undermine the foundation of the research by failing to provide the necessary context and justification for the study.

Inadequate Literature Review: There has been some research on the relationship between exercise and mental health. This paper will investigate this relationship further.

• Problem : This review is too general and does not provide sufficient detail about the existing research or how it informs the current study.

Example with Adequate Literature Review: Research has consistently shown that regular physical activity has positive effects on mental health. For example, a study by Gujral et al. (2019) demonstrated that aerobic exercise can significantly reduce symptoms of depression and anxiety. Similarly, Smith and Lee (2020) found that strength training also contributes to improved mood and reduced stress levels. However, much of the existing research has focused on adult populations, with relatively few studies examining these effects in adolescents. Additionally, the specific types of exercise that are most beneficial for different mental health outcomes have not been thoroughly investigated. This study aims to explore the effects of various types of exercise on the mental health of high school students, thereby addressing these gaps in the literature.(5-6)

• Be Comprehensive : Review a broad range of studies related to the research topic to provide a thorough context.
• Be Specific : Cite specific studies, including their methodologies, findings, and relevance to the current research.
• Be Critical : Analyze and evaluate the existing research, identifying strengths, weaknesses, and gaps.
• Be Structured : Organize the literature review logically, grouping studies by themes or findings to create a coherent narrative.
• Be Relevant : Focus on the most relevant studies that directly relate to the research question and objectives.

Ignoring the research gap in a research paper introduction means failing to identify and articulate what specific aspect of the topic has not been explored or adequately addressed in existing literature. The research gap is a critical component because it justifies the necessity and originality of the study. Without highlighting this gap, the research may appear redundant or lacking in significance.

How huge is this mistake?

• Lack of Justification : The study may not appear necessary or relevant, diminishing its perceived value.
• Redundancy : The research may seem to duplicate existing studies, offering no new insights or contributions to the field. Even if you are using methodology similar to previous studies, it is important to note why you are doing so e.g., few studies have used that specific methodology, and you would like to validate it in your sample population!
• Reader Disinterest : Readers may lose interest if they do not see the unique contribution or purpose of the research.

Example of Ignoring the Research Gap: Many studies have examined the effects of exercise on mental health. This paper looks at the relationship between physical activity and depression.

• Problem : This introduction does not specify what aspect of the relationship between physical activity and depression has not been studied, failing to highlight the unique contribution of the research.

Example of Identifying the Research Gap: Numerous studies have demonstrated the general benefits of physical activity on mental health, particularly its role in alleviating symptoms of depression. However, there is limited research on how different types of exercise (e.g., aerobic vs. anaerobic) specifically impact depression levels among various age groups. This study investigates the differential effects of aerobic and anaerobic exercise on depression in young adults, aiming to fill this gap in the literature.(6)

• Conduct a Thorough Literature Review : Understand the current state of research in your field to identify what has been studied and where gaps exist.
• Be Specific : Clearly articulate what specific aspect has not been covered in existing studies.
• Link to Your Study : Explain how your research will address this gap and contribute to the field.
• Use Evidence : Support your identification of the gap with references to previous studies.
• Emphasize Significance : Highlight why filling this gap is important for advancing knowledge or practical applications.

Overly technical language refers to the excessive use of jargon, complex terms, and highly specialized language that may be difficult for readers, especially those not familiar with the field, to understand. While technical language is sometimes necessary in academic writing, overusing it in the introduction can create several problems:

• Reader Alienation : Readers may find the text intimidating or inaccessible, leading to disengagement.
• Lack of Clarity : The main points and significance of the research can become obscured by complex terminology.
• Reduced Impact : The research may fail to communicate its importance effectively if readers struggle to understand the introduction.

Example of Overly Technical Language: The present study examines the metacognitive strategies employed by individuals in the domain of second language acquisition, specifically focusing on the interaction between declarative and procedural memory systems in the process of syntactic parsing.

• Problem : This sentence is loaded with jargon (“metacognitive strategies,” “second language acquisition,” “declarative and procedural memory systems,” “syntactic parsing”), which can be overwhelming and confusing for readers not familiar with these terms.

Example with Simplified Language: This study looks at the thinking strategies people use when learning a second language. It focuses on how different types of memory, such as the knowledge of facts and the skills for doing things, help in understanding sentence structures.(7)

• Know Your Audience : Tailor the language to the intended audience, ensuring it is accessible to both specialists and non-specialists.
• Define Term s: When technical terms are necessary, provide clear definitions or explanations.
• Use Analogies : Simplify complex concepts using analogies or examples that are easy to understand.
• Avoid Jargon : Limit the use of jargon and specialized terms, especially in the introduction.
• Seek Feedback : Ask peers or non-experts to read the introduction and provide feedback on clarity and accessibility.

Curious about delving into research but unsure where to begin?

Poor organization and flow in a research paper introduction refer to a lack of logical structure and coherence that makes the introduction difficult to follow. This can occur when ideas are presented in a haphazard manner, transitions between sections are weak or non-existent, and the overall narrative is disjointed. A well-organized introduction should smoothly guide the reader from the general context to the specific objectives of the study.

Example of Poor Organization and Flow: “Climate change affects agriculture in various ways. Many studies have looked at the impact on crop yields. This paper will discuss the economic implications of these changes. Climate models predict increased variability in weather patterns, which will affect water availability. Researchers have found that higher temperatures reduce the growing season for many crops.”

• Problem : The ideas are presented in a scattered manner without clear connections. The mention of economic implications seems out of place, and there are abrupt shifts between topics.

Example with Good Organization and Flow: Climate change poses significant challenges to agriculture by altering weather patterns, impacting crop yields, and affecting water availability. Numerous studies have shown that increased temperatures can shorten the growing season for many crops, leading to reduced yields. Additionally, climate models predict increased variability in weather patterns, which complicates water management for farmers. These changes not only affect food production but also have substantial economic implications for agricultural communities. This paper will examine the economic impacts of climate-induced changes in agriculture, focusing on crop yield variability and water resource management.(1)

• Create an Outline : Before writing, outline the main points you want to cover in the introduction.
• Think in terms of an inverted triangle : Begin broadly to introduce basic concepts related to your topic. As you progress through the introduction, you can introduce more and more specific topics until you have enough information to justify your thesis statement
• Use Transitional Phrases : Employ transitional phrases and sentences to connect ideas and sections smoothly.
• Follow a Logical Sequence : Present information in a logical order, moving from general context to specific objectives.
• Maintain Focus : Stay focused on the main topic and avoid introducing unrelated ideas.
• Revise for Coherence : Review and revise the introduction to ensure that it flows well and that each part contributes to the overall narrative.

Neglecting the audience refers to failing to consider the background, knowledge level, and interests of the intended readers when writing the introduction of a research paper. This mistake can manifest in several ways, such as using overly technical language for a general audience, providing insufficient background information for readers unfamiliar with the topic, or failing to engage the readers’ interest.

Example of Neglecting the Audience: For experts in genomic sequencing, this study explores the epigenetic modifications resulting from CRISPR-Cas9 interventions, focusing on the methylation patterns and histone modifications observed in gene-edited cells.

• Problem : This introduction assumes a high level of expertise in genomic sequencing and epigenetics, which may alienate readers without this background.

Example with Audience Consideration: CRISPR-Cas9 is a groundbreaking tool in genetic research that allows scientists to edit DNA with precision. However, altering genes can lead to unexpected changes in how genes are expressed, known as epigenetic modifications. This study investigates these changes by looking at specific markers on DNA, such as methylation patterns, and how they affect gene activity in cells that have been edited using CRISPR-Cas9. Our goal is to understand the broader implications of gene editing on cellular functions, which is crucial for advancing medical research and treatments.(8)

• Identify the Audience : Determine who the intended readers are (e.g., experts, students, general public) and tailor the language and content accordingly. Read papers from the journals you are considering for submission. Professional editors curate the language used in these papers and are a great starting point to identify the level of expertise of your audience!
• Simplify Language : Use clear and straightforward language, avoiding jargon and technical terms unless they are necessary and well-explained.
• Provide Background Information : Include sufficient background information to help readers understand the context and significance of the research.
• Engage the Reader : Start with an engaging introduction that highlights the relevance and importance of the research topic.
• Anticipate Questions : Consider what questions or concerns the audience might have and address them in the introduction

Writing a Research Paper Introduction (with 3 Examples)

Nail your research paper's introduction! Learn to captivate and inform readers from the start—our guide shows how!

TABLE OF CONTENTS

A catchy and informative introduction is essential in academic writing, especially if you want your readers to have background information about your paper. However, writing an interesting and informative introduction can sometimes be a time-consuming and tiring process. If you don't know where to start when crafting an introduction, no need to worry - we've got you covered!

In this article, we will explain step by step what an introduction is in academic writing and how to write it!

Ready? Let's start!

• An introduction is a paragraph that provides information about your entire paper and aims to attract and inform the reader.
• Before writing an introduction or even starting your paper, you need to research academic sources.
• The first one or two sentences of an introduction paragraph should be a hook to attract the reader's attention.
• Afterwards, you need to prepare the reader for your argument by giving background information about your topic.
• Finally, you should state your argument about your topic with a thesis statement.
• If you are writing a longer paper, you can inform your readers about the map of your paper.
• If you are looking for an AI assistant to support you throughout your writing process, TextCortex is designed for you with its advanced features.

What is an Introduction in a research paper?

In any academic writing, including essays and research papers, an introduction is the first paragraph that the reader will encounter. This paragraph should both attract the reader's attention and give them the necessary information about the paper. In any academic paper, the introduction paragraph constitutes 10% of the paper's total word count. For example, if you are preparing a 3,000-word paper, your introduction paragraph should consist of approximately 300 words. You should also write sentences within these 300 words that will attract the reader's attention and provide them with information about the paper.

Importance of an Introduction Paragraph

The biggest function of an introduction paragraph is to prepare the reader for the author's thesis statement. A traditional introduction paragraph begins with a few sentences or questions that will catch the reader's attention. After attracting the reader's attention, necessary background information on the subject is given. Finally, the author explains to the readers what the whole paper is about by stating the thesis. A thesis statement is the final sentence that summarizes the main points of your paper and conveys your claim.

First Things First: Preliminary Research

When working on any academic writing type, it is essential to start by researching your topic thoroughly before beginning to type. What sets academic writing apart from other writing types is the requirement for it to be written using accurate information from reliable sources.

Researching academic sources can be a time-consuming and unnecessary process. One has to read through hundreds of pages, review dozens of articles and verify the accuracy of each source. However, if you're looking to reduce your workload and maximize efficiency by automating repetitive tasks such as literature review, ZenoChat is the perfect solution for you. With its web search feature, ZenoChat can use the entire internet as a data source. Additionally, by activating the "scholar" option of the ZenoChat web search feature, you can ensure that it only uses academic sources when generating output.

How to Create an Introduction for Academic Writing?

Creating an introduction paragraph that is interesting, informative, and conveys your thesis is an easier process than it seems. As long as you have sufficient information about your topic and an outline , you can write engaging introductions by following a few simple steps. Let's take a closer look at how to write an introduction for academic writing.

1-) Start with a Catchy Hook

Your first sentence is one of the factors that most influence a reader's decision to read your paper. This sentence determines the tone of your paper and attracts the reader's attention. For this reason, we recommend that you start your introduction paragraph with a strong and catchy hook sentence.

• Avoid long and complex sentences
• Use clear and concise sentences
• Write a sentence that will spark the reader's curiosity
• You can ask questions that will encourage the reader to read the remaining paragraph
• Avoid fact or overly broad sentences
• Avoid using dictionary definitions as your hook

2-) Give Background Information

After writing a strong hook sentence, you need to provide basic information about your topic so that the reader can understand what they will learn about when they read your paper. In this section, you can benefit from opinions that support or oppose your argument. Additionally, this section should refer to the body paragraphs of your writing.

• You can write a background information sentence for each body paragraph.
• The information here should be concise and compact
• Avoid talking about your evidence and results unless necessary.

3-) State Your Thesis 

After attracting the reader's attention and providing background information, it is time to present your approach and argument towards the topic with a thesis statement. A thesis statement usually comprises one or two sentences and communicates the paper's argument to the reader. A well-written thesis statement should express your stance on the topic.

• Avoid merely stating a fact
• Claim your argument

4-) Tell Reader About Your Paper

Although you need to move on to body paragraphs after the thesis statement in short papers, it will be useful to add a few sentences that will guide the reader in your longer papers. This way, your readers can better understand which arguments they will encounter on which pages and the course of your paper. That leads the reader to clearly understand and follow your content.

Let’s Wrap it Up

Writing an interesting and informative introduction is usually a long process that requires a lot of rewriting. You may need to rewrite a sentence dozens of times so that your words and sentences clearly describe your paper and argument. Fortunately, you can generate state-of-the-art introductions using AI tools and use them with a little editing.

Research Paper Introduction Examples

Looking for research paper introduction examples? Quotes, anecdotes, questions, examples, and broad statements—all of them can be used successfully to write an introduction for a research paper. It’s instructive to see them in action, in the hands of skilled academic writers.

Let’s begin with David M. Kennedy’s superb history, Freedom from Fear: The American People in Depression and War, 1929–1945 . Kennedy begins each chapter with a quote, followed by his text. The quote above chapter 1 shows President Hoover speaking in 1928 about America’s golden future. The text below it begins with the stock market collapse of 1929. It is a riveting account of just how wrong Hoover was. The text about the Depression is stronger because it contrasts so starkly with the optimistic quotation.

“We in America today are nearer the final triumph over poverty than ever before in the history of any land.”—Herbert Hoover, August 11, 1928 Like an earthquake, the stock market crash of October 1929 cracked startlingly across the United States, the herald of a crisis that was to shake the American way of life to its foundations. The events of the ensuing decade opened a fissure across the landscape of American history no less gaping than that opened by the volley on Lexington Common in April 1775 or by the bombardment of Sumter on another April four score and six years later. (adsbygoogle = window.adsbygoogle || []).push({}); The ratcheting ticker machines in the autumn of 1929 did not merely record avalanching stock prices. In time they came also to symbolize the end of an era. (David M. Kennedy, Freedom from Fear: The American People in Depression and War, 1929–1945 . New York: Oxford University Press, 1999, p. 10)

Kennedy has exciting, wrenching material to work with. John Mueller faces the exact opposite problem. In Retreat from Doomsday: The Obsolescence of Major War , he is trying to explain why Great Powers have suddenly stopped fighting each other. For centuries they made war on each other with devastating regularity, killing millions in the process. But now, Mueller thinks, they have not just paused; they have stopped permanently. He is literally trying to explain why “nothing is happening now.” That may be an exciting topic intellectually, it may have great practical significance, but “nothing happened” is not a very promising subject for an exciting opening paragraph. Mueller manages to make it exciting and, at the same time, shows why it matters so much. Here’s his opening, aptly entitled “History’s Greatest Nonevent”:

On May 15, 1984, the major countries of the developed world had managed to remain at peace with each other for the longest continuous stretch of time since the days of the Roman Empire. If a significant battle in a war had been fought on that day, the press would have bristled with it. As usual, however, a landmark crossing in the history of peace caused no stir: the most prominent story in the New York Times that day concerned the saga of a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest. This book seeks to develop an explanation for what is probably the greatest nonevent in human history. (John Mueller, Retreat from Doomsday: The Obsolescence of Major War . New York: Basic Books, 1989, p. 3)

In the space of a few sentences, Mueller sets up his puzzle and reveals its profound human significance. At the same time, he shows just how easy it is to miss this milestone in the buzz of daily events. Notice how concretely he does that. He doesn’t just say that the New York Times ignored this record setting peace. He offers telling details about what they covered instead: “a manicurist, a machinist, and a cleaning woman who had just won a big Lotto contest.” Likewise, David Kennedy immediately entangles us in concrete events: the stunning stock market crash of 1929. These are powerful openings that capture readers’ interests, establish puzzles, and launch narratives.

Sociologist James Coleman begins in a completely different way, by posing the basic questions he will study. His ambitious book, Foundations of Social Theory , develops a comprehensive theory of social life, so it is entirely appropriate for him to begin with some major questions. But he could just as easily have begun with a compelling story or anecdote. He includes many of them elsewhere in his book. His choice for the opening, though, is to state his major themes plainly and frame them as a paradox. Sociologists, he says, are interested in aggregate behavior—how people act in groups, organizations, or large numbers—yet they mostly examine individuals:

A central problem in social science is that of accounting for the function of some kind of social system. Yet in most social research, observations are not made on the system as a whole, but on some part of it. In fact, the natural unit of observation is the individual person…  This has led to a widening gap between theory and research… (James S. Coleman, Foundations of Social Theory . Cambridge, MA: Harvard University Press, 1990, pp. 1–2)

After expanding on this point, Coleman explains that he will not try to remedy the problem by looking solely at groups or aggregate-level data. That’s a false solution, he says, because aggregates don’t act; individuals do. So the real problem is to show the links between individual actions and aggregate outcomes, between the micro and the macro.

The major problem for explanations of system behavior based on actions and orientations at a level below that of the system [in this case, on individual-level actions] is that of moving from the lower level to the system level. This has been called the micro-to-macro problem, and it is pervasive throughout the social sciences. (Coleman, Foundations of Social Theory , p. 6)

Explaining how to deal with this “micro-to-macro problem” is the central issue of Coleman’s book, and he announces it at the beginning.

Coleman’s theory-driven opening stands at the opposite end of the spectrum from engaging stories or anecdotes, which are designed to lure the reader into the narrative and ease the path to a more analytic treatment later in the text. Take, for example, the opening sentences of Robert L. Herbert’s sweeping study Impressionism: Art, Leisure, and Parisian Society : “When Henry Tuckerman came to Paris in 1867, one of the thousands of Americans attracted there by the huge international exposition, he was bowled over by the extraordinary changes since his previous visit twenty years before.” (Robert L. Herbert, Impressionism: Art, Leisure, and Parisian Society . New Haven, CT: Yale University Press, 1988, p. 1.) Herbert fills in the evocative details to set the stage for his analysis of the emerging Impressionist art movement and its connection to Parisian society and leisure in this period.

David Bromwich writes about Wordsworth, a poet so familiar to students of English literature that it is hard to see him afresh, before his great achievements, when he was just a young outsider starting to write. To draw us into Wordsworth’s early work, Bromwich wants us to set aside our entrenched images of the famous mature poet and see him as he was in the 1790s, as a beginning writer on the margins of society. He accomplishes this ambitious task in the opening sentences of Disowned by Memory: Wordsworth’s Poetry of the 1790s :

Wordsworth turned to poetry after the revolution to remind himself that he was still a human being. It was a curious solution, to a difficulty many would not have felt. The whole interest of his predicament is that he did feel it. Yet Wordsworth is now so established an eminence—his name so firmly fixed with readers as a moralist of self-trust emanating from complete self-security—that it may seem perverse to imagine him as a criminal seeking expiation. Still, that is a picture we get from The Borderers and, at a longer distance, from “Tintern Abbey.” (David Bromwich, Disowned by Memory: Wordsworth’s Poetry of the 1790s . Chicago: University of Chicago Press, 1998, p. 1)

That’s a wonderful opening! Look at how much Bromwich accomplishes in just a few words. He not only prepares the way for analyzing Wordsworth’s early poetry; he juxtaposes the anguished young man who wrote it to the self-confident, distinguished figure he became—the eminent man we can’t help remembering as we read his early poetry.

Let us highlight a couple of other points in this passage because they illustrate some intelligent writing choices. First, look at the odd comma in this sentence: “It was a curious solution, to a difficulty many would not have felt.” Any standard grammar book would say that comma is wrong and should be omitted. Why did Bromwich insert it? Because he’s a fine writer, thinking of his sentence rhythm and the point he wants to make. The comma does exactly what it should. It makes us pause, breaking the sentence into two parts, each with an interesting point. One is that Wordsworth felt a difficulty others would not have; the other is that he solved it in a distinctive way. It would be easy for readers to glide over this double message, so Bromwich has inserted a speed bump to slow us down. Most of the time, you should follow grammatical rules, like those about commas, but you should bend them when it serves a good purpose. That’s what the writer does here.

The second small point is the phrase “after the revolution” in the first sentence: “Wordsworth turned to poetry after the revolution to remind himself that he was still a human being.” Why doesn’t Bromwich say “after the French Revolution”? Because he has judged his book’s audience. He is writing for specialists who already know which revolution is reverberating through English life in the 1790s. It is the French Revolution, not the earlier loss of the American colonies. If Bromwich were writing for a much broader audience—say, the New York Times Book Review—he would probably insert the extra word to avoid confusion.

The message “Know your audience” applies to all writers. Don’t talk down to them by assuming they can’t get dressed in the morning. Don’t strut around showing off your book learnin’ by tossing in arcane facts and esoteric language for its own sake. Neither will win over readers.

Bromwich, Herbert, and Coleman open their works in different ways, but their choices work well for their different texts. Your task is to decide what kind of opening will work best for yours. Don’t let that happen by default, by grabbing the first idea you happen upon. Consider a couple of different ways of opening your thesis and then choose the one you prefer. Give yourself some options, think them over, then make an informed choice.

Using the Introduction to Map out Your Writing

Whether you begin with a story, puzzle, or broad statement, the next part of the research paper introduction should pose your main questions and establish your argument. This is your thesis statement—your viewpoint along with the supporting reasons and evidence. It should be articulated plainly so readers understand full well what your paper is about and what it will argue.

After that, give your readers a road map of what’s to come. That’s normally done at the end of the introductory section (or, in a book, at the end of the introductory chapter). Here’s John J. Mearsheimer presenting such a road map in The Tragedy of Great Power Politics . He not only tells us the order of upcoming chapters, he explains why he’s chosen that order and which chapters are most important:

The Plan of the Book The rest of the chapters in this book are concerned mainly with answering the six big questions about power which I identified earlier. Chapter 2, which is probably the most important chapter in the book, lays out my theory of why states compete for power and why they pursue hegemony. In Chapters 3 and 4, I define power and explain how to measure it. I do this in order to lay the groundwork for testing my theory… (John J. Mearsheimer, The Tragedy of Great Power Politics . New York: W. W. Norton, 2001, p. 27)

As this excerpt makes clear, Mearsheimer has already laid out his “six big questions” in the research paper introduction. Now he’s showing us the path ahead, the path to answering those questions.

At the end of the research paper introduction, give your readers a road map of what’s to come. Tell them what the upcoming sections will be and why they are arranged in this particular order.

How to write an effective introduction for your research paper

Last updated

20 January 2024

Reviewed by

However, the introduction is a vital element of your research paper . It helps the reader decide whether your paper is worth their time. As such, it's worth taking your time to get it right.

In this article, we'll tell you everything you need to know about writing an effective introduction for your research paper.

• The importance of an introduction in research papers

The primary purpose of an introduction is to provide an overview of your paper. This lets readers gauge whether they want to continue reading or not. The introduction should provide a meaningful roadmap of your research to help them make this decision. It should let readers know whether the information they're interested in is likely to be found in the pages that follow.

Aside from providing readers with information about the content of your paper, the introduction also sets the tone. It shows readers the style of language they can expect, which can further help them to decide how far to read.

When you take into account both of these roles that an introduction plays, it becomes clear that crafting an engaging introduction is the best way to get your paper read more widely. First impressions count, and the introduction provides that impression to readers.

• The optimum length for a research paper introduction

While there's no magic formula to determine exactly how long a research paper introduction should be, there are a few guidelines. Some variables that impact the ideal introduction length include:

Field of study

Complexity of the topic

Specific requirements of the course or publication

A commonly recommended length of a research paper introduction is around 10% of the total paper’s length. So, a ten-page paper has a one-page introduction. If the topic is complex, it may require more background to craft a compelling intro. Humanities papers tend to have longer introductions than those of the hard sciences.

The best way to craft an introduction of the right length is to focus on clarity and conciseness. Tell the reader only what is necessary to set up your research. An introduction edited down with this goal in mind should end up at an acceptable length.

• Evaluating successful research paper introductions

A good way to gauge how to create a great introduction is by looking at examples from across your field. The most influential and well-regarded papers should provide some insights into what makes a good introduction.

Dissecting examples: what works and why

We can make some general assumptions by looking at common elements of a good introduction, regardless of the field of research.

A common structure is to start with a broad context, and then narrow that down to specific research questions or hypotheses. This creates a funnel that establishes the scope and relevance.

The most effective introductions are careful about the assumptions they make regarding reader knowledge. By clearly defining key terms and concepts instead of assuming the reader is familiar with them, these introductions set a more solid foundation for understanding.

To pull in the reader and make that all-important good first impression, excellent research paper introductions will often incorporate a compelling narrative or some striking fact that grabs the reader's attention.

Finally, good introductions provide clear citations from past research to back up the claims they're making. In the case of argumentative papers or essays (those that take a stance on a topic or issue), a strong thesis statement compels the reader to continue reading.

Common pitfalls to avoid in research paper introductions

You can also learn what not to do by looking at other research papers. Many authors have made mistakes you can learn from.

We've talked about the need to be clear and concise. Many introductions fail at this; they're verbose, vague, or otherwise fail to convey the research problem or hypothesis efficiently. This often comes in the form of an overemphasis on background information, which obscures the main research focus.

Ensure your introduction provides the proper emphasis and excitement around your research and its significance. Otherwise, fewer people will want to read more about it.

• Crafting a compelling introduction for a research paper

Let’s take a look at the steps required to craft an introduction that pulls readers in and compels them to learn more about your research.

Step 1: Capturing interest and setting the scene

To capture the reader's interest immediately, begin your introduction with a compelling question, a surprising fact, a provocative quote, or some other mechanism that will hook readers and pull them further into the paper.

As they continue reading, the introduction should contextualize your research within the current field, showing readers its relevance and importance. Clarify any essential terms that will help them better understand what you're saying. This keeps the fundamentals of your research accessible to all readers from all backgrounds.

Step 2: Building a solid foundation with background information

Including background information in your introduction serves two major purposes:

It helps to clarify the topic for the reader

It establishes the depth of your research

The approach you take when conveying this information depends on the type of paper.

For argumentative papers, you'll want to develop engaging background narratives. These should provide context for the argument you'll be presenting.

For empirical papers, highlighting past research is the key. Often, there will be some questions that weren't answered in those past papers. If your paper is focused on those areas, those papers make ideal candidates for you to discuss and critique in your introduction.

Step 3: Pinpointing the research challenge

To capture the attention of the reader, you need to explain what research challenges you'll be discussing.

For argumentative papers, this involves articulating why the argument you'll be making is important. What is its relevance to current discussions or problems? What is the potential impact of people accepting or rejecting your argument?

For empirical papers, explain how your research is addressing a gap in existing knowledge. What new insights or contributions will your research bring to your field?

Step 4: Clarifying your research aims and objectives

We mentioned earlier that the introduction to a research paper can serve as a roadmap for what's within. We've also frequently discussed the need for clarity. This step addresses both of these.

When writing an argumentative paper, craft a thesis statement with impact. Clearly articulate what your position is and the main points you intend to present. This will map out for the reader exactly what they'll get from reading the rest.

For empirical papers, focus on formulating precise research questions and hypotheses. Directly link them to the gaps or issues you've identified in existing research to show the reader the precise direction your research paper will take.

Step 5: Sketching the blueprint of your study

Continue building a roadmap for your readers by designing a structured outline for the paper. Guide the reader through your research journey, explaining what the different sections will contain and their relationship to one another.

This outline should flow seamlessly as you move from section to section. Creating this outline early can also help guide the creation of the paper itself, resulting in a final product that's better organized. In doing so, you'll craft a paper where each section flows intuitively from the next.

Step 6: Integrating your research question

To avoid letting your research question get lost in background information or clarifications, craft your introduction in such a way that the research question resonates throughout. The research question should clearly address a gap in existing knowledge or offer a new perspective on an existing problem.

Tell users your research question explicitly but also remember to frequently come back to it. When providing context or clarification, point out how it relates to the research question. This keeps your focus where it needs to be and prevents the topic of the paper from becoming under-emphasized.

Step 7: Establishing the scope and limitations

So far, we've talked mostly about what's in the paper and how to convey that information to readers. The opposite is also important. Information that's outside the scope of your paper should be made clear to the reader in the introduction so their expectations for what is to follow are set appropriately.

Similarly, be honest and upfront about the limitations of the study. Any constraints in methodology, data, or how far your findings can be generalized should be fully communicated in the introduction.

Step 8: Concluding the introduction with a promise

The final few lines of the introduction are your last chance to convince people to continue reading the rest of the paper. Here is where you should make it very clear what benefit they'll get from doing so. What topics will be covered? What questions will be answered? Make it clear what they will get for continuing.

By providing a quick recap of the key points contained in the introduction in its final lines and properly setting the stage for what follows in the rest of the paper, you refocus the reader's attention on the topic of your research and guide them to read more.

• Research paper introduction best practices

Following the steps above will give you a compelling introduction that hits on all the key points an introduction should have. Some more tips and tricks can make an introduction even more polished.

As you follow the steps above, keep the following tips in mind.

Set the right tone and style

Like every piece of writing, a research paper should be written for the audience. That is to say, it should match the tone and style that your academic discipline and target audience expect. This is typically a formal and academic tone, though the degree of formality varies by field.

Kno w the audience

The perfect introduction balances clarity with conciseness. The amount of clarification required for a given topic depends greatly on the target audience. Knowing who will be reading your paper will guide you in determining how much background information is required.

Adopt the CARS (create a research space) model

The CARS model is a helpful tool for structuring introductions. This structure has three parts. The beginning of the introduction establishes the general research area. Next, relevant literature is reviewed and critiqued. The final section outlines the purpose of your study as it relates to the previous parts.

Master the art of funneling

The CARS method is one example of a well-funneled introduction. These start broadly and then slowly narrow down to your specific research problem. It provides a nice narrative flow that provides the right information at the right time. If you stray from the CARS model, try to retain this same type of funneling.

Incorporate narrative element

People read research papers largely to be informed. But to inform the reader, you have to hold their attention. A narrative style, particularly in the introduction, is a great way to do that. This can be a compelling story, an intriguing question, or a description of a real-world problem.

Write the introduction last

By writing the introduction after the rest of the paper, you'll have a better idea of what your research entails and how the paper is structured. This prevents the common problem of writing something in the introduction and then forgetting to include it in the paper. It also means anything particularly exciting in the paper isn’t neglected in the intro.

How to Write an Introduction for a Research Paper

Table of Contents

Writing an introduction for a research paper is a critical element of your paper, but it can seem challenging to encapsulate enormous amount of information into a concise form. The introduction of your research paper sets the tone for your research and provides the context for your study. In this article, we will guide you through the process of writing an effective introduction that grabs the reader's attention and captures the essence of your research paper.

Understanding the Purpose of a Research Paper Introduction

The introduction acts as a road map for your research paper, guiding the reader through the main ideas and arguments. The purpose of the introduction is to present your research topic to the readers and provide a rationale for why your study is relevant. It helps the reader locate your research and its relevance in the broader field of related scientific explorations. Additionally, the introduction should inform the reader about the objectives and scope of your study, giving them an overview of what to expect in the paper. By including a comprehensive introduction, you establish your credibility as an author and convince the reader that your research is worth their time and attention.

Key Elements to Include in Your Introduction

When writing your research paper introduction, there are several key elements you should include to ensure it is comprehensive and informative.

• A hook or attention-grabbing statement to capture the reader's interest.  It can be a thought-provoking question, a surprising statistic, or a compelling anecdote that relates to your research topic.
• A brief overview of the research topic and its significance. By highlighting the gap in existing knowledge or the problem your research aims to address, you create a compelling case for the relevance of your study.
• A clear research question or problem statement. This serves as the foundation of your research and guides the reader in understanding the unique focus of your study. It should be concise, specific, and clearly articulated.
• An outline of the paper's structure and main arguments, to help the readers navigate through the paper with ease.

Preparing to Write Your Introduction

Before diving into writing your introduction, it is essential to prepare adequately. This involves 3 important steps:

• Conducting Preliminary Research: Immerse yourself in the existing literature to develop a clear research question and position your study within the academic discourse.
• Identifying Your Thesis Statement: Define a specific, focused, and debatable thesis statement, serving as a roadmap for your paper.
• Considering Broader Context: Reflect on the significance of your research within your field, understanding its potential impact and contribution.

By engaging in these preparatory steps, you can ensure that your introduction is well-informed, focused, and sets the stage for a compelling research paper.

Structuring Your Introduction

Now that you have prepared yourself to tackle the introduction, it's time to structure it effectively. A well-structured introduction will engage the reader from the beginning and provide a logical flow to your research paper.

Starting with a Hook

Begin your introduction with an attention-grabbing hook that captivates the reader's interest. This hook serves as a way to make your introduction more engaging and compelling. For example, if you are writing a research paper on the impact of climate change on biodiversity, you could start your introduction with a statistic about the number of species that have gone extinct due to climate change. This will immediately grab the reader's attention and make them realize the urgency and importance of the topic.

Introducing Your Topic

Provide a brief overview, which should give the reader a general understanding of the subject matter and its significance. Explain the importance of the topic and its relevance to the field. This will help the reader understand why your research is significant and why they should continue reading. Continuing with the example of climate change and biodiversity, you could explain how climate change is one of the greatest threats to global biodiversity, how it affects ecosystems, and the potential consequences for both wildlife and human populations. By providing this context, you are setting the stage for the rest of your research paper and helping the reader understand the importance of your study.

Presenting Your Thesis Statement

The thesis statement should directly address your research question and provide a preview of the main arguments or findings discussed in your paper. Make sure your thesis statement is clear, concise, and well-supported by the evidence you will present in your research paper. By presenting a strong and focused thesis statement, you are providing the reader with the information they could anticipate in your research paper. This will help them understand the purpose and scope of your study and will make them more inclined to continue reading.

Writing Techniques for an Effective Introduction

When crafting an introduction, it is crucial to pay attention to the finer details that can elevate your writing to the next level. By utilizing specific writing techniques, you can captivate your readers and draw them into your research journey.

Using Clear and Concise Language

One of the most important writing techniques to employ in your introduction is the use of clear and concise language. By choosing your words carefully, you can effectively convey your ideas to the reader. It is essential to avoid using jargon or complex terminology that may confuse or alienate your audience. Instead, focus on communicating your research in a straightforward manner to ensure that your introduction is accessible to both experts in your field and those who may be new to the topic. This approach allows you to engage a broader audience and make your research more inclusive.

Establishing the Relevance of Your Research

One way to establish the relevance of your research is by highlighting how it fills a gap in the existing literature. Explain how your study addresses a significant research question that has not been adequately explored. By doing this, you demonstrate that your research is not only unique but also contributes to the broader knowledge in your field. Furthermore, it is important to emphasize the potential impact of your research. Whether it is advancing scientific understanding, informing policy decisions, or improving practical applications, make it clear to the reader how your study can make a difference.

By employing these two writing techniques in your introduction, you can effectively engage your readers. Take your time to craft an introduction that is both informative and captivating, leaving your readers eager to delve deeper into your research.

Revising and Polishing Your Introduction

Once you have written your introduction, it is crucial to revise and polish it to ensure that it effectively sets the stage for your research paper.

Self-Editing Techniques

Review your introduction for clarity, coherence, and logical flow. Ensure each paragraph introduces a new idea or argument with smooth transitions.

Check for grammatical errors, spelling mistakes, and awkward sentence structures.

Ensure that your introduction aligns with the overall tone and style of your research paper.

Seeking Feedback for Improvement

Consider seeking feedback from peers, colleagues, or your instructor. They can provide valuable insights and suggestions for improving your introduction. Be open to constructive criticism and use it to refine your introduction and make it more compelling for the reader.

Writing an introduction for a research paper requires careful thought and planning. By understanding the purpose of the introduction, preparing adequately, structuring effectively, and employing writing techniques, you can create an engaging and informative introduction for your research. Remember to revise and polish your introduction to ensure that it accurately represents the main ideas and arguments in your research paper. With a well-crafted introduction, you will capture the reader's attention and keep them inclined to your paper.

In addition to anecdotes, you should incorporate relevant statistics or data. It infuses credibility and significance into the introduction. Numbers possess a persuasive power, shedding light on the magnitude of an issue and underscoring the urgency of the report’s focus.

Coupled with compelling quotes, they entice readers to contemplate the broader implications of the subject matter.

5. Providing Context for the Report

You should first delve into the background and history of the topic to provide readers with a comprehensive understanding of its evolution over time. This historical perspective lays the groundwork for appreciating the report’s relevance in the present context.

Moreover, describing the current relevance and significance of the topic bridges the gap between theory and practice. It highlights the practical implications and real-world applications, enticing readers to explore further. In addition to how to write a report introduction, it is essential to address the previous research or related studies to showcase the existing body of knowledge and identify gaps that the current report aims to fill.

How to Write a Research Introduction

Last Updated: December 6, 2023 Fact Checked

This article was co-authored by Megan Morgan, PhD . Megan Morgan is a Graduate Program Academic Advisor in the School of Public & International Affairs at the University of Georgia. She earned her PhD in English from the University of Georgia in 2015. There are 7 references cited in this article, which can be found at the bottom of the page. This article has been fact-checked, ensuring the accuracy of any cited facts and confirming the authority of its sources. This article has been viewed 2,656,547 times.

The introduction to a research paper can be the most challenging part of the paper to write. The length of the introduction will vary depending on the type of research paper you are writing. An introduction should announce your topic, provide context and a rationale for your work, before stating your research questions and hypothesis. Well-written introductions set the tone for the paper, catch the reader's interest, and communicate the hypothesis or thesis statement.

Introducing the Topic of the Paper

• In scientific papers this is sometimes known as an "inverted triangle", where you start with the broadest material at the start, before zooming in on the specifics. [2] X Research source
• The sentence "Throughout the 20th century, our views of life on other planets have drastically changed" introduces a topic, but does so in broad terms.
• It provides the reader with an indication of the content of the essay and encourages them to read on.

• For example, if you were writing a paper about the behaviour of mice when exposed to a particular substance, you would include the word "mice", and the scientific name of the relevant compound in the first sentences.
• If you were writing a history paper about the impact of the First World War on gender relations in Britain, you should mention those key words in your first few lines.

• This is especially important if you are attempting to develop a new conceptualization that uses language and terminology your readers may be unfamiliar with.

• If you use an anecdote ensure that is short and highly relevant for your research. It has to function in the same way as an alternative opening, namely to announce the topic of your research paper to your reader.
• For example, if you were writing a sociology paper about re-offending rates among young offenders, you could include a brief story of one person whose story reflects and introduces your topic.
• This kind of approach is generally not appropriate for the introduction to a natural or physical sciences research paper where the writing conventions are different.

Establishing the Context for Your Paper

• It is important to be concise in the introduction, so provide an overview on recent developments in the primary research rather than a lengthy discussion.
• You can follow the "inverted triangle" principle to focus in from the broader themes to those to which you are making a direct contribution with your paper.
• A strong literature review presents important background information to your own research and indicates the importance of the field.

• By making clear reference to existing work you can demonstrate explicitly the specific contribution you are making to move the field forward.
• You can identify a gap in the existing scholarship and explain how you are addressing it and moving understanding forward.

• For example, if you are writing a scientific paper you could stress the merits of the experimental approach or models you have used.
• Stress what is novel in your research and the significance of your new approach, but don't give too much detail in the introduction.
• A stated rationale could be something like: "the study evaluates the previously unknown anti-inflammatory effects of a topical compound in order to evaluate its potential clinical uses".

Specifying Your Research Questions and Hypothesis

• The research question or questions generally come towards the end of the introduction, and should be concise and closely focused.
• The research question might recall some of the key words established in the first few sentences and the title of your paper.
• An example of a research question could be "what were the consequences of the North American Free Trade Agreement on the Mexican export economy?"
• This could be honed further to be specific by referring to a particular element of the Free Trade Agreement and the impact on a particular industry in Mexico, such as clothing manufacture.
• A good research question should shape a problem into a testable hypothesis.

• If possible try to avoid using the word "hypothesis" and rather make this implicit in your writing. This can make your writing appear less formulaic.
• In a scientific paper, giving a clear one-sentence overview of your results and their relation to your hypothesis makes the information clear and accessible. [10] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source
• An example of a hypothesis could be "mice deprived of food for the duration of the study were expected to become more lethargic than those fed normally".

• This is not always necessary and you should pay attention to the writing conventions in your discipline.
• In a natural sciences paper, for example, there is a fairly rigid structure which you will be following.
• A humanities or social science paper will most likely present more opportunities to deviate in how you structure your paper.

Understand the assignment, choose a research paper topic, conduct preliminary research, develop a thesis statement, create a research paper outline, write a first draft of the research paper, write the introduction, write a compelling body of text, write the conclusion, the second draft, the revision process, research paper checklist, free lecture slides.

Completing a research paper successfully means accomplishing the specific tasks set out for you. Before you start, make sure you thoroughly understanding the assignment task sheet:

• Read it carefully, looking for anything confusing you might need to clarify with your professor.
• Identify the assignment goal, deadline, length specifications, formatting, and submission method.
• Make a bulleted list of the key points, then go back and cross completed items off as you’re writing.

Carefully consider your timeframe and word limit: be realistic, and plan enough time to research, write, and edit.

There are many ways to generate an idea for a research paper, from brainstorming with pen and paper to talking it through with a fellow student or professor.

You can try free writing, which involves taking a broad topic and writing continuously for two or three minutes to identify absolutely anything relevant that could be interesting.

You can also gain inspiration from other research. The discussion or recommendations sections of research papers often include ideas for other specific topics that require further examination.

Once you have a broad subject area, narrow it down to choose a topic that interests you, m eets the criteria of your assignment, and i s possible to research. Aim for ideas that are both original and specific:

• A paper following the chronology of World War II would not be original or specific enough.
• A paper on the experience of Danish citizens living close to the German border during World War II would be specific and could be original enough.

Note any discussions that seem important to the topic, and try to find an issue that you can focus your paper around. Use a variety of sources , including journals, books, and reliable websites, to ensure you do not miss anything glaring.

Do not only verify the ideas you have in mind, but look for sources that contradict your point of view.

• Is there anything people seem to overlook in the sources you research?
• Are there any heated debates you can address?
• Do you have a unique take on your topic?
• Have there been some recent developments that build on the extant research?

In this stage, you might find it helpful to formulate some research questions to help guide you. To write research questions, try to finish the following sentence: “I want to know how/what/why…”

A thesis statement is a statement of your central argument — it establishes the purpose and position of your paper. If you started with a research question, the thesis statement should answer it. It should also show what evidence and reasoning you’ll use to support that answer.

The thesis statement should be concise, contentious, and coherent. That means it should briefly summarize your argument in a sentence or two, make a claim that requires further evidence or analysis, and make a coherent point that relates to every part of the paper.

You will probably revise and refine the thesis statement as you do more research, but it can serve as a guide throughout the writing process. Every paragraph should aim to support and develop this central claim.

A research paper outline is essentially a list of the key topics, arguments, and evidence you want to include, divided into sections with headings so that you know roughly what the paper will look like before you start writing.

A structure outline can help make the writing process much more efficient, so it’s worth dedicating some time to create one.

Your first draft won’t be perfect — you can polish later on. Your priorities at this stage are as follows:

• Maintaining forward momentum — write now, perfect later.
• Paying attention to clear organization and logical ordering of paragraphs and sentences, which will help when you come to the second draft.
• Expressing your ideas as clearly as possible, so you know what you were trying to say when you come back to the text.

You do not need to start by writing the introduction. Begin where it feels most natural for you — some prefer to finish the most difficult sections first, while others choose to start with the easiest part. If you created an outline, use it as a map while you work.

Do not delete large sections of text. If you begin to dislike something you have written or find it doesn’t quite fit, move it to a different document, but don’t lose it completely — you never know if it might come in useful later.

Paragraph structure

Paragraphs are the basic building blocks of research papers. Each one should focus on a single claim or idea that helps to establish the overall argument or purpose of the paper.

Example paragraph

George Orwell’s 1946 essay “Politics and the English Language” has had an enduring impact on thought about the relationship between politics and language. This impact is particularly obvious in light of the various critical review articles that have recently referenced the essay. For example, consider Mark Falcoff’s 2009 article in The National Review Online, “The Perversion of Language; or, Orwell Revisited,” in which he analyzes several common words (“activist,” “civil-rights leader,” “diversity,” and more). Falcoff’s close analysis of the ambiguity built into political language intentionally mirrors Orwell’s own point-by-point analysis of the political language of his day. Even 63 years after its publication, Orwell’s essay is emulated by contemporary thinkers.

Citing sources

It’s also important to keep track of citations at this stage to avoid accidental plagiarism . Each time you use a source, make sure to take note of where the information came from.

The research paper introduction should address three questions: What, why, and how? After finishing the introduction, the reader should know what the paper is about, why it is worth reading, and how you’ll build your arguments.

What? Be specific about the topic of the paper, introduce the background, and define key terms or concepts.

Why? This is the most important, but also the most difficult, part of the introduction. Try to provide brief answers to the following questions: What new material or insight are you offering? What important issues does your essay help define or answer?

How? To let the reader know what to expect from the rest of the paper, the introduction should include a “map” of what will be discussed, briefly presenting the key elements of the paper in chronological order.

The major struggle faced by most writers is how to organize the information presented in the paper, which is one reason an outline is so useful. However, remember that the outline is only a guide and, when writing, you can be flexible with the order in which the information and arguments are presented.

One way to stay on track is to use your thesis statement and topic sentences . Check:

• topic sentences against the thesis statement;
• topic sentences against each other, for similarities and logical ordering;
• and each sentence against the topic sentence of that paragraph.

Be aware of paragraphs that seem to cover the same things. If two paragraphs discuss something similar, they must approach that topic in different ways. Aim to create smooth transitions between sentences, paragraphs, and sections.

The research paper conclusion is designed to help your reader out of the paper’s argument, giving them a sense of finality.

Trace the course of the paper, emphasizing how it all comes together to prove your thesis statement. Give the paper a sense of finality by making sure the reader understands how you’ve settled the issues raised in the introduction.

You might also discuss the more general consequences of the argument, outline what the paper offers to future students of the topic, and suggest any questions the paper’s argument raises but cannot or does not try to answer.

You should not :

• Offer new arguments or essential information
• Take up any more space than necessary
• Begin with stock phrases that signal you are ending the paper (e.g. “In conclusion”)

There are four main considerations when it comes to the second draft.

• Check how your vision of the paper lines up with the first draft and, more importantly, that your paper still answers the assignment.
• Identify any assumptions that might require (more substantial) justification, keeping your reader’s perspective foremost in mind. Remove these points if you cannot substantiate them further.
• Be open to rearranging your ideas. Check whether any sections feel out of place and whether your ideas could be better organized.
• If you find that old ideas do not fit as well as you anticipated, you should cut them out or condense them. You might also find that new and well-suited ideas occurred to you during the writing of the first draft — now is the time to make them part of the paper.

The goal during the revision and proofreading process is to ensure you have completed all the necessary tasks and that the paper is as well-articulated as possible. You can speed up the proofreading process by using the AI proofreader .

Global concerns

• Confirm that your paper completes every task specified in your assignment sheet.
• Check for logical organization and flow of paragraphs.
• Check paragraphs against the introduction and thesis statement.

Fine-grained details

Check the content of each paragraph, making sure that:

• each sentence helps support the topic sentence.
• no unnecessary or irrelevant information is present.
• all technical terms your audience might not know are identified.

Next, think about sentence structure , grammatical errors, and formatting . Check that you have correctly used transition words and phrases to show the connections between your ideas. Look for typos, cut unnecessary words, and check for consistency in aspects such as heading formatting and spellings .

Finally, you need to make sure your paper is correctly formatted according to the rules of the citation style you are using. For example, you might need to include an MLA heading  or create an APA title page .

Research Report

Definition:

Research Report is a written document that presents the results of a research project or study, including the research question, methodology, results, and conclusions, in a clear and objective manner.

The purpose of a research report is to communicate the findings of the research to the intended audience, which could be other researchers, stakeholders, or the general public.

Components of Research Report

Components of Research Report are as follows:

Introduction

The introduction sets the stage for the research report and provides a brief overview of the research question or problem being investigated. It should include a clear statement of the purpose of the study and its significance or relevance to the field of research. It may also provide background information or a literature review to help contextualize the research.

Literature Review

The literature review provides a critical analysis and synthesis of the existing research and scholarship relevant to the research question or problem. It should identify the gaps, inconsistencies, and contradictions in the literature and show how the current study addresses these issues. The literature review also establishes the theoretical framework or conceptual model that guides the research.

Methodology

The methodology section describes the research design, methods, and procedures used to collect and analyze data. It should include information on the sample or participants, data collection instruments, data collection procedures, and data analysis techniques. The methodology should be clear and detailed enough to allow other researchers to replicate the study.

The results section presents the findings of the study in a clear and objective manner. It should provide a detailed description of the data and statistics used to answer the research question or test the hypothesis. Tables, graphs, and figures may be included to help visualize the data and illustrate the key findings.

The discussion section interprets the results of the study and explains their significance or relevance to the research question or problem. It should also compare the current findings with those of previous studies and identify the implications for future research or practice. The discussion should be based on the results presented in the previous section and should avoid speculation or unfounded conclusions.

The conclusion summarizes the key findings of the study and restates the main argument or thesis presented in the introduction. It should also provide a brief overview of the contributions of the study to the field of research and the implications for practice or policy.

The references section lists all the sources cited in the research report, following a specific citation style, such as APA or MLA.

The appendices section includes any additional material, such as data tables, figures, or instruments used in the study, that could not be included in the main text due to space limitations.

Types of Research Report

Types of Research Report are as follows:

Thesis is a type of research report. A thesis is a long-form research document that presents the findings and conclusions of an original research study conducted by a student as part of a graduate or postgraduate program. It is typically written by a student pursuing a higher degree, such as a Master’s or Doctoral degree, although it can also be written by researchers or scholars in other fields.

Research Paper

Research paper is a type of research report. A research paper is a document that presents the results of a research study or investigation. Research papers can be written in a variety of fields, including science, social science, humanities, and business. They typically follow a standard format that includes an introduction, literature review, methodology, results, discussion, and conclusion sections.

Technical Report

A technical report is a detailed report that provides information about a specific technical or scientific problem or project. Technical reports are often used in engineering, science, and other technical fields to document research and development work.

Progress Report

A progress report provides an update on the progress of a research project or program over a specific period of time. Progress reports are typically used to communicate the status of a project to stakeholders, funders, or project managers.

Feasibility Report

A feasibility report assesses the feasibility of a proposed project or plan, providing an analysis of the potential risks, benefits, and costs associated with the project. Feasibility reports are often used in business, engineering, and other fields to determine the viability of a project before it is undertaken.

Field Report

A field report documents observations and findings from fieldwork, which is research conducted in the natural environment or setting. Field reports are often used in anthropology, ecology, and other social and natural sciences.

Title: The Impact of Social Media on Academic Performance among High School Students

This study aims to investigate the relationship between social media use and academic performance among high school students. The study utilized a quantitative research design, which involved a survey questionnaire administered to a sample of 200 high school students. The findings indicate that there is a negative correlation between social media use and academic performance, suggesting that excessive social media use can lead to poor academic performance among high school students. The results of this study have important implications for educators, parents, and policymakers, as they highlight the need for strategies that can help students balance their social media use and academic responsibilities.

Introduction:

Social media has become an integral part of the lives of high school students. With the widespread use of social media platforms such as Facebook, Twitter, Instagram, and Snapchat, students can connect with friends, share photos and videos, and engage in discussions on a range of topics. While social media offers many benefits, concerns have been raised about its impact on academic performance. Many studies have found a negative correlation between social media use and academic performance among high school students (Kirschner & Karpinski, 2010; Paul, Baker, & Cochran, 2012).

Given the growing importance of social media in the lives of high school students, it is important to investigate its impact on academic performance. This study aims to address this gap by examining the relationship between social media use and academic performance among high school students.

Methodology:

The study utilized a quantitative research design, which involved a survey questionnaire administered to a sample of 200 high school students. The questionnaire was developed based on previous studies and was designed to measure the frequency and duration of social media use, as well as academic performance.

The participants were selected using a convenience sampling technique, and the survey questionnaire was distributed in the classroom during regular school hours. The data collected were analyzed using descriptive statistics and correlation analysis.

The findings indicate that the majority of high school students use social media platforms on a daily basis, with Facebook being the most popular platform. The results also show a negative correlation between social media use and academic performance, suggesting that excessive social media use can lead to poor academic performance among high school students.

Discussion:

The results of this study have important implications for educators, parents, and policymakers. The negative correlation between social media use and academic performance suggests that strategies should be put in place to help students balance their social media use and academic responsibilities. For example, educators could incorporate social media into their teaching strategies to engage students and enhance learning. Parents could limit their children’s social media use and encourage them to prioritize their academic responsibilities. Policymakers could develop guidelines and policies to regulate social media use among high school students.

Conclusion:

In conclusion, this study provides evidence of the negative impact of social media on academic performance among high school students. The findings highlight the need for strategies that can help students balance their social media use and academic responsibilities. Further research is needed to explore the specific mechanisms by which social media use affects academic performance and to develop effective strategies for addressing this issue.

Limitations:

One limitation of this study is the use of convenience sampling, which limits the generalizability of the findings to other populations. Future studies should use random sampling techniques to increase the representativeness of the sample. Another limitation is the use of self-reported measures, which may be subject to social desirability bias. Future studies could use objective measures of social media use and academic performance, such as tracking software and school records.

Implications:

The findings of this study have important implications for educators, parents, and policymakers. Educators could incorporate social media into their teaching strategies to engage students and enhance learning. For example, teachers could use social media platforms to share relevant educational resources and facilitate online discussions. Parents could limit their children’s social media use and encourage them to prioritize their academic responsibilities. They could also engage in open communication with their children to understand their social media use and its impact on their academic performance. Policymakers could develop guidelines and policies to regulate social media use among high school students. For example, schools could implement social media policies that restrict access during class time and encourage responsible use.

Applications of Research Report

Research reports have many applications, including:

• Communicating research findings: The primary application of a research report is to communicate the results of a study to other researchers, stakeholders, or the general public. The report serves as a way to share new knowledge, insights, and discoveries with others in the field.
• Informing policy and practice : Research reports can inform policy and practice by providing evidence-based recommendations for decision-makers. For example, a research report on the effectiveness of a new drug could inform regulatory agencies in their decision-making process.
• Supporting further research: Research reports can provide a foundation for further research in a particular area. Other researchers may use the findings and methodology of a report to develop new research questions or to build on existing research.
• Evaluating programs and interventions : Research reports can be used to evaluate the effectiveness of programs and interventions in achieving their intended outcomes. For example, a research report on a new educational program could provide evidence of its impact on student performance.
• Demonstrating impact : Research reports can be used to demonstrate the impact of research funding or to evaluate the success of research projects. By presenting the findings and outcomes of a study, research reports can show the value of research to funders and stakeholders.
• Enhancing professional development : Research reports can be used to enhance professional development by providing a source of information and learning for researchers and practitioners in a particular field. For example, a research report on a new teaching methodology could provide insights and ideas for educators to incorporate into their own practice.

How to write Research Report

Here are some steps you can follow to write a research report:

• Identify the research question: The first step in writing a research report is to identify your research question. This will help you focus your research and organize your findings.
• Conduct research : Once you have identified your research question, you will need to conduct research to gather relevant data and information. This can involve conducting experiments, reviewing literature, or analyzing data.
• Organize your findings: Once you have gathered all of your data, you will need to organize your findings in a way that is clear and understandable. This can involve creating tables, graphs, or charts to illustrate your results.
• Write the report: Once you have organized your findings, you can begin writing the report. Start with an introduction that provides background information and explains the purpose of your research. Next, provide a detailed description of your research methods and findings. Finally, summarize your results and draw conclusions based on your findings.
• Proofread and edit: After you have written your report, be sure to proofread and edit it carefully. Check for grammar and spelling errors, and make sure that your report is well-organized and easy to read.
• Include a reference list: Be sure to include a list of references that you used in your research. This will give credit to your sources and allow readers to further explore the topic if they choose.
• Format your report: Finally, format your report according to the guidelines provided by your instructor or organization. This may include formatting requirements for headings, margins, fonts, and spacing.

Purpose of Research Report

The purpose of a research report is to communicate the results of a research study to a specific audience, such as peers in the same field, stakeholders, or the general public. The report provides a detailed description of the research methods, findings, and conclusions.

Some common purposes of a research report include:

• Sharing knowledge: A research report allows researchers to share their findings and knowledge with others in their field. This helps to advance the field and improve the understanding of a particular topic.
• Identifying trends: A research report can identify trends and patterns in data, which can help guide future research and inform decision-making.
• Addressing problems: A research report can provide insights into problems or issues and suggest solutions or recommendations for addressing them.
• Evaluating programs or interventions : A research report can evaluate the effectiveness of programs or interventions, which can inform decision-making about whether to continue, modify, or discontinue them.
• Meeting regulatory requirements: In some fields, research reports are required to meet regulatory requirements, such as in the case of drug trials or environmental impact studies.

When to Write Research Report

A research report should be written after completing the research study. This includes collecting data, analyzing the results, and drawing conclusions based on the findings. Once the research is complete, the report should be written in a timely manner while the information is still fresh in the researcher’s mind.

In academic settings, research reports are often required as part of coursework or as part of a thesis or dissertation. In this case, the report should be written according to the guidelines provided by the instructor or institution.

In other settings, such as in industry or government, research reports may be required to inform decision-making or to comply with regulatory requirements. In these cases, the report should be written as soon as possible after the research is completed in order to inform decision-making in a timely manner.

Overall, the timing of when to write a research report depends on the purpose of the research, the expectations of the audience, and any regulatory requirements that need to be met. However, it is important to complete the report in a timely manner while the information is still fresh in the researcher’s mind.

Characteristics of Research Report

There are several characteristics of a research report that distinguish it from other types of writing. These characteristics include:

• Objective: A research report should be written in an objective and unbiased manner. It should present the facts and findings of the research study without any personal opinions or biases.
• Systematic: A research report should be written in a systematic manner. It should follow a clear and logical structure, and the information should be presented in a way that is easy to understand and follow.
• Detailed: A research report should be detailed and comprehensive. It should provide a thorough description of the research methods, results, and conclusions.
• Accurate : A research report should be accurate and based on sound research methods. The findings and conclusions should be supported by data and evidence.
• Organized: A research report should be well-organized. It should include headings and subheadings to help the reader navigate the report and understand the main points.
• Clear and concise: A research report should be written in clear and concise language. The information should be presented in a way that is easy to understand, and unnecessary jargon should be avoided.
• Citations and references: A research report should include citations and references to support the findings and conclusions. This helps to give credit to other researchers and to provide readers with the opportunity to further explore the topic.

Advantages of Research Report

Research reports have several advantages, including:

• Communicating research findings: Research reports allow researchers to communicate their findings to a wider audience, including other researchers, stakeholders, and the general public. This helps to disseminate knowledge and advance the understanding of a particular topic.
• Providing evidence for decision-making : Research reports can provide evidence to inform decision-making, such as in the case of policy-making, program planning, or product development. The findings and conclusions can help guide decisions and improve outcomes.
• Supporting further research: Research reports can provide a foundation for further research on a particular topic. Other researchers can build on the findings and conclusions of the report, which can lead to further discoveries and advancements in the field.
• Demonstrating expertise: Research reports can demonstrate the expertise of the researchers and their ability to conduct rigorous and high-quality research. This can be important for securing funding, promotions, and other professional opportunities.
• Meeting regulatory requirements: In some fields, research reports are required to meet regulatory requirements, such as in the case of drug trials or environmental impact studies. Producing a high-quality research report can help ensure compliance with these requirements.

Chapter 11: Presenting Your Research

Writing a Research Report in American Psychological Association (APA) Style

Learning Objectives

• Identify the major sections of an APA-style research report and the basic contents of each section.
• Plan and write an effective APA-style research report.

In this section, we look at how to write an APA-style empirical research report , an article that presents the results of one or more new studies. Recall that the standard sections of an empirical research report provide a kind of outline. Here we consider each of these sections in detail, including what information it contains, how that information is formatted and organized, and tips for writing each section. At the end of this section is a sample APA-style research report that illustrates many of these principles.

Sections of a Research Report

Title page and abstract.

An APA-style research report begins with a  title page . The title is centred in the upper half of the page, with each important word capitalized. The title should clearly and concisely (in about 12 words or fewer) communicate the primary variables and research questions. This sometimes requires a main title followed by a subtitle that elaborates on the main title, in which case the main title and subtitle are separated by a colon. Here are some titles from recent issues of professional journals published by the American Psychological Association.

• Sex Differences in Coping Styles and Implications for Depressed Mood
• Effects of Aging and Divided Attention on Memory for Items and Their Contexts
• Computer-Assisted Cognitive Behavioural Therapy for Child Anxiety: Results of a Randomized Clinical Trial
• Virtual Driving and Risk Taking: Do Racing Games Increase Risk-Taking Cognitions, Affect, and Behaviour?

Below the title are the authors’ names and, on the next line, their institutional affiliation—the university or other institution where the authors worked when they conducted the research. As we have already seen, the authors are listed in an order that reflects their contribution to the research. When multiple authors have made equal contributions to the research, they often list their names alphabetically or in a randomly determined order.

In some areas of psychology, the titles of many empirical research reports are informal in a way that is perhaps best described as “cute.” They usually take the form of a play on words or a well-known expression that relates to the topic under study. Here are some examples from recent issues of the Journal Psychological Science .

• “Smells Like Clean Spirit: Nonconscious Effects of Scent on Cognition and Behavior”
• “Time Crawls: The Temporal Resolution of Infants’ Visual Attention”
• “Scent of a Woman: Men’s Testosterone Responses to Olfactory Ovulation Cues”
• “Apocalypse Soon?: Dire Messages Reduce Belief in Global Warming by Contradicting Just-World Beliefs”
• “Serial vs. Parallel Processing: Sometimes They Look Like Tweedledum and Tweedledee but They Can (and Should) Be Distinguished”
• “How Do I Love Thee? Let Me Count the Words: The Social Effects of Expressive Writing”

Individual researchers differ quite a bit in their preference for such titles. Some use them regularly, while others never use them. What might be some of the pros and cons of using cute article titles?

For articles that are being submitted for publication, the title page also includes an author note that lists the authors’ full institutional affiliations, any acknowledgments the authors wish to make to agencies that funded the research or to colleagues who commented on it, and contact information for the authors. For student papers that are not being submitted for publication—including theses—author notes are generally not necessary.

The  abstract  is a summary of the study. It is the second page of the manuscript and is headed with the word  Abstract . The first line is not indented. The abstract presents the research question, a summary of the method, the basic results, and the most important conclusions. Because the abstract is usually limited to about 200 words, it can be a challenge to write a good one.

Introduction

The  introduction  begins on the third page of the manuscript. The heading at the top of this page is the full title of the manuscript, with each important word capitalized as on the title page. The introduction includes three distinct subsections, although these are typically not identified by separate headings. The opening introduces the research question and explains why it is interesting, the literature review discusses relevant previous research, and the closing restates the research question and comments on the method used to answer it.

The Opening

The  opening , which is usually a paragraph or two in length, introduces the research question and explains why it is interesting. To capture the reader’s attention, researcher Daryl Bem recommends starting with general observations about the topic under study, expressed in ordinary language (not technical jargon)—observations that are about people and their behaviour (not about researchers or their research; Bem, 2003 [1] ). Concrete examples are often very useful here. According to Bem, this would be a poor way to begin a research report:

Festinger’s theory of cognitive dissonance received a great deal of attention during the latter part of the 20th century (p. 191)

The following would be much better:

The individual who holds two beliefs that are inconsistent with one another may feel uncomfortable. For example, the person who knows that he or she enjoys smoking but believes it to be unhealthy may experience discomfort arising from the inconsistency or disharmony between these two thoughts or cognitions. This feeling of discomfort was called cognitive dissonance by social psychologist Leon Festinger (1957), who suggested that individuals will be motivated to remove this dissonance in whatever way they can (p. 191).

After capturing the reader’s attention, the opening should go on to introduce the research question and explain why it is interesting. Will the answer fill a gap in the literature? Will it provide a test of an important theory? Does it have practical implications? Giving readers a clear sense of what the research is about and why they should care about it will motivate them to continue reading the literature review—and will help them make sense of it.

Breaking the Rules

Researcher Larry Jacoby reported several studies showing that a word that people see or hear repeatedly can seem more familiar even when they do not recall the repetitions—and that this tendency is especially pronounced among older adults. He opened his article with the following humourous anecdote:

A friend whose mother is suffering symptoms of Alzheimer’s disease (AD) tells the story of taking her mother to visit a nursing home, preliminary to her mother’s moving there. During an orientation meeting at the nursing home, the rules and regulations were explained, one of which regarded the dining room. The dining room was described as similar to a fine restaurant except that tipping was not required. The absence of tipping was a central theme in the orientation lecture, mentioned frequently to emphasize the quality of care along with the advantages of having paid in advance. At the end of the meeting, the friend’s mother was asked whether she had any questions. She replied that she only had one question: “Should I tip?” (Jacoby, 1999, p. 3)

Although both humour and personal anecdotes are generally discouraged in APA-style writing, this example is a highly effective way to start because it both engages the reader and provides an excellent real-world example of the topic under study.

The Literature Review

Immediately after the opening comes the  literature review , which describes relevant previous research on the topic and can be anywhere from several paragraphs to several pages in length. However, the literature review is not simply a list of past studies. Instead, it constitutes a kind of argument for why the research question is worth addressing. By the end of the literature review, readers should be convinced that the research question makes sense and that the present study is a logical next step in the ongoing research process.

Like any effective argument, the literature review must have some kind of structure. For example, it might begin by describing a phenomenon in a general way along with several studies that demonstrate it, then describing two or more competing theories of the phenomenon, and finally presenting a hypothesis to test one or more of the theories. Or it might describe one phenomenon, then describe another phenomenon that seems inconsistent with the first one, then propose a theory that resolves the inconsistency, and finally present a hypothesis to test that theory. In applied research, it might describe a phenomenon or theory, then describe how that phenomenon or theory applies to some important real-world situation, and finally suggest a way to test whether it does, in fact, apply to that situation.

Looking at the literature review in this way emphasizes a few things. First, it is extremely important to start with an outline of the main points that you want to make, organized in the order that you want to make them. The basic structure of your argument, then, should be apparent from the outline itself. Second, it is important to emphasize the structure of your argument in your writing. One way to do this is to begin the literature review by summarizing your argument even before you begin to make it. “In this article, I will describe two apparently contradictory phenomena, present a new theory that has the potential to resolve the apparent contradiction, and finally present a novel hypothesis to test the theory.” Another way is to open each paragraph with a sentence that summarizes the main point of the paragraph and links it to the preceding points. These opening sentences provide the “transitions” that many beginning researchers have difficulty with. Instead of beginning a paragraph by launching into a description of a previous study, such as “Williams (2004) found that…,” it is better to start by indicating something about why you are describing this particular study. Here are some simple examples:

Another example of this phenomenon comes from the work of Williams (2004).

Williams (2004) offers one explanation of this phenomenon.

An alternative perspective has been provided by Williams (2004).

We used a method based on the one used by Williams (2004).

Finally, remember that your goal is to construct an argument for why your research question is interesting and worth addressing—not necessarily why your favourite answer to it is correct. In other words, your literature review must be balanced. If you want to emphasize the generality of a phenomenon, then of course you should discuss various studies that have demonstrated it. However, if there are other studies that have failed to demonstrate it, you should discuss them too. Or if you are proposing a new theory, then of course you should discuss findings that are consistent with that theory. However, if there are other findings that are inconsistent with it, again, you should discuss them too. It is acceptable to argue that the  balance  of the research supports the existence of a phenomenon or is consistent with a theory (and that is usually the best that researchers in psychology can hope for), but it is not acceptable to  ignore contradictory evidence. Besides, a large part of what makes a research question interesting is uncertainty about its answer.

The Closing

The  closing  of the introduction—typically the final paragraph or two—usually includes two important elements. The first is a clear statement of the main research question or hypothesis. This statement tends to be more formal and precise than in the opening and is often expressed in terms of operational definitions of the key variables. The second is a brief overview of the method and some comment on its appropriateness. Here, for example, is how Darley and Latané (1968) [2] concluded the introduction to their classic article on the bystander effect:

These considerations lead to the hypothesis that the more bystanders to an emergency, the less likely, or the more slowly, any one bystander will intervene to provide aid. To test this proposition it would be necessary to create a situation in which a realistic “emergency” could plausibly occur. Each subject should also be blocked from communicating with others to prevent his getting information about their behaviour during the emergency. Finally, the experimental situation should allow for the assessment of the speed and frequency of the subjects’ reaction to the emergency. The experiment reported below attempted to fulfill these conditions. (p. 378)

Thus the introduction leads smoothly into the next major section of the article—the method section.

The  method section  is where you describe how you conducted your study. An important principle for writing a method section is that it should be clear and detailed enough that other researchers could replicate the study by following your “recipe.” This means that it must describe all the important elements of the study—basic demographic characteristics of the participants, how they were recruited, whether they were randomly assigned, how the variables were manipulated or measured, how counterbalancing was accomplished, and so on. At the same time, it should avoid irrelevant details such as the fact that the study was conducted in Classroom 37B of the Industrial Technology Building or that the questionnaire was double-sided and completed using pencils.

The method section begins immediately after the introduction ends with the heading “Method” (not “Methods”) centred on the page. Immediately after this is the subheading “Participants,” left justified and in italics. The participants subsection indicates how many participants there were, the number of women and men, some indication of their age, other demographics that may be relevant to the study, and how they were recruited, including any incentives given for participation.

After the participants section, the structure can vary a bit. Figure 11.1 shows three common approaches. In the first, the participants section is followed by a design and procedure subsection, which describes the rest of the method. This works well for methods that are relatively simple and can be described adequately in a few paragraphs. In the second approach, the participants section is followed by separate design and procedure subsections. This works well when both the design and the procedure are relatively complicated and each requires multiple paragraphs.

What is the difference between design and procedure? The design of a study is its overall structure. What were the independent and dependent variables? Was the independent variable manipulated, and if so, was it manipulated between or within subjects? How were the variables operationally defined? The procedure is how the study was carried out. It often works well to describe the procedure in terms of what the participants did rather than what the researchers did. For example, the participants gave their informed consent, read a set of instructions, completed a block of four practice trials, completed a block of 20 test trials, completed two questionnaires, and were debriefed and excused.

In the third basic way to organize a method section, the participants subsection is followed by a materials subsection before the design and procedure subsections. This works well when there are complicated materials to describe. This might mean multiple questionnaires, written vignettes that participants read and respond to, perceptual stimuli, and so on. The heading of this subsection can be modified to reflect its content. Instead of “Materials,” it can be “Questionnaires,” “Stimuli,” and so on.

The  results section  is where you present the main results of the study, including the results of the statistical analyses. Although it does not include the raw data—individual participants’ responses or scores—researchers should save their raw data and make them available to other researchers who request them. Several journals now encourage the open sharing of raw data online.

Although there are no standard subsections, it is still important for the results section to be logically organized. Typically it begins with certain preliminary issues. One is whether any participants or responses were excluded from the analyses and why. The rationale for excluding data should be described clearly so that other researchers can decide whether it is appropriate. A second preliminary issue is how multiple responses were combined to produce the primary variables in the analyses. For example, if participants rated the attractiveness of 20 stimulus people, you might have to explain that you began by computing the mean attractiveness rating for each participant. Or if they recalled as many items as they could from study list of 20 words, did you count the number correctly recalled, compute the percentage correctly recalled, or perhaps compute the number correct minus the number incorrect? A third preliminary issue is the reliability of the measures. This is where you would present test-retest correlations, Cronbach’s α, or other statistics to show that the measures are consistent across time and across items. A final preliminary issue is whether the manipulation was successful. This is where you would report the results of any manipulation checks.

The results section should then tackle the primary research questions, one at a time. Again, there should be a clear organization. One approach would be to answer the most general questions and then proceed to answer more specific ones. Another would be to answer the main question first and then to answer secondary ones. Regardless, Bem (2003) [3] suggests the following basic structure for discussing each new result:

• Remind the reader of the research question.
• Give the answer to the research question in words.
• Present the relevant statistics.
• Qualify the answer if necessary.
• Summarize the result.

Notice that only Step 3 necessarily involves numbers. The rest of the steps involve presenting the research question and the answer to it in words. In fact, the basic results should be clear even to a reader who skips over the numbers.

The  discussion  is the last major section of the research report. Discussions usually consist of some combination of the following elements:

• Summary of the research
• Theoretical implications
• Practical implications
• Limitations
• Suggestions for future research

The discussion typically begins with a summary of the study that provides a clear answer to the research question. In a short report with a single study, this might require no more than a sentence. In a longer report with multiple studies, it might require a paragraph or even two. The summary is often followed by a discussion of the theoretical implications of the research. Do the results provide support for any existing theories? If not, how  can  they be explained? Although you do not have to provide a definitive explanation or detailed theory for your results, you at least need to outline one or more possible explanations. In applied research—and often in basic research—there is also some discussion of the practical implications of the research. How can the results be used, and by whom, to accomplish some real-world goal?

The theoretical and practical implications are often followed by a discussion of the study’s limitations. Perhaps there are problems with its internal or external validity. Perhaps the manipulation was not very effective or the measures not very reliable. Perhaps there is some evidence that participants did not fully understand their task or that they were suspicious of the intent of the researchers. Now is the time to discuss these issues and how they might have affected the results. But do not overdo it. All studies have limitations, and most readers will understand that a different sample or different measures might have produced different results. Unless there is good reason to think they  would have, however, there is no reason to mention these routine issues. Instead, pick two or three limitations that seem like they could have influenced the results, explain how they could have influenced the results, and suggest ways to deal with them.

Most discussions end with some suggestions for future research. If the study did not satisfactorily answer the original research question, what will it take to do so? What  new  research questions has the study raised? This part of the discussion, however, is not just a list of new questions. It is a discussion of two or three of the most important unresolved issues. This means identifying and clarifying each question, suggesting some alternative answers, and even suggesting ways they could be studied.

Finally, some researchers are quite good at ending their articles with a sweeping or thought-provoking conclusion. Darley and Latané (1968) [4] , for example, ended their article on the bystander effect by discussing the idea that whether people help others may depend more on the situation than on their personalities. Their final sentence is, “If people understand the situational forces that can make them hesitate to intervene, they may better overcome them” (p. 383). However, this kind of ending can be difficult to pull off. It can sound overreaching or just banal and end up detracting from the overall impact of the article. It is often better simply to end when you have made your final point (although you should avoid ending on a limitation).

The references section begins on a new page with the heading “References” centred at the top of the page. All references cited in the text are then listed in the format presented earlier. They are listed alphabetically by the last name of the first author. If two sources have the same first author, they are listed alphabetically by the last name of the second author. If all the authors are the same, then they are listed chronologically by the year of publication. Everything in the reference list is double-spaced both within and between references.

Appendices, Tables, and Figures

Appendices, tables, and figures come after the references. An  appendix  is appropriate for supplemental material that would interrupt the flow of the research report if it were presented within any of the major sections. An appendix could be used to present lists of stimulus words, questionnaire items, detailed descriptions of special equipment or unusual statistical analyses, or references to the studies that are included in a meta-analysis. Each appendix begins on a new page. If there is only one, the heading is “Appendix,” centred at the top of the page. If there is more than one, the headings are “Appendix A,” “Appendix B,” and so on, and they appear in the order they were first mentioned in the text of the report.

After any appendices come tables and then figures. Tables and figures are both used to present results. Figures can also be used to illustrate theories (e.g., in the form of a flowchart), display stimuli, outline procedures, and present many other kinds of information. Each table and figure appears on its own page. Tables are numbered in the order that they are first mentioned in the text (“Table 1,” “Table 2,” and so on). Figures are numbered the same way (“Figure 1,” “Figure 2,” and so on). A brief explanatory title, with the important words capitalized, appears above each table. Each figure is given a brief explanatory caption, where (aside from proper nouns or names) only the first word of each sentence is capitalized. More details on preparing APA-style tables and figures are presented later in the book.

Sample APA-Style Research Report

Figures 11.2, 11.3, 11.4, and 11.5 show some sample pages from an APA-style empirical research report originally written by undergraduate student Tomoe Suyama at California State University, Fresno. The main purpose of these figures is to illustrate the basic organization and formatting of an APA-style empirical research report, although many high-level and low-level style conventions can be seen here too.

Key Takeaways

• An APA-style empirical research report consists of several standard sections. The main ones are the abstract, introduction, method, results, discussion, and references.
• The introduction consists of an opening that presents the research question, a literature review that describes previous research on the topic, and a closing that restates the research question and comments on the method. The literature review constitutes an argument for why the current study is worth doing.
• The method section describes the method in enough detail that another researcher could replicate the study. At a minimum, it consists of a participants subsection and a design and procedure subsection.
• The results section describes the results in an organized fashion. Each primary result is presented in terms of statistical results but also explained in words.
• The discussion typically summarizes the study, discusses theoretical and practical implications and limitations of the study, and offers suggestions for further research.
• Practice: Look through an issue of a general interest professional journal (e.g.,  Psychological Science ). Read the opening of the first five articles and rate the effectiveness of each one from 1 ( very ineffective ) to 5 ( very effective ). Write a sentence or two explaining each rating.
• Practice: Find a recent article in a professional journal and identify where the opening, literature review, and closing of the introduction begin and end.
• Practice: Find a recent article in a professional journal and highlight in a different colour each of the following elements in the discussion: summary, theoretical implications, practical implications, limitations, and suggestions for future research.

Long Descriptions

Figure 11.1 long description: Table showing three ways of organizing an APA-style method section.

In the simple method, there are two subheadings: “Participants” (which might begin “The participants were…”) and “Design and procedure” (which might begin “There were three conditions…”).

In the typical method, there are three subheadings: “Participants” (“The participants were…”), “Design” (“There were three conditions…”), and “Procedure” (“Participants viewed each stimulus on the computer screen…”).

In the complex method, there are four subheadings: “Participants” (“The participants were…”), “Materials” (“The stimuli were…”), “Design” (“There were three conditions…”), and “Procedure” (“Participants viewed each stimulus on the computer screen…”). [Return to Figure 11.1]

The Dreaded Introductory Paragraph

Writing the introductory paragraph can be a frustrating and slow process -- but it doesn't have to be.  If you planned your paper out, then most of the introductory paragraph is already written.  Now you just need a beginning and an end.

Here's an introductory paragraph for a paper I wrote.  I started the paper with a factoid, then presented each main point of my paper and then ended with my thesis statement.

Research Paper Introduction Example: Academic Writing Insight

How to write an introductory paragraph for research paper.

The writing of the research paper is a multi-aspect process. Because this type of academic assignment consists of several parts. If you fail to complete one of the levels, you will fail the whole paper.

Introduction is not a Literal Beginning

As you know, the hardest part is just to begin the paper. And what should do student at the beginning? Not writing an outline. And not working on the introduction. He should make massive research on his topic . You cannot start writing an introduction without having a personal view on the issue that you are going to study. You have to prepare for introduction writing though analyzing facts available online and making notes. If it’s hard to do it yourself, the  online essay help service by Edusson.com will solve this problem instantly!

Why do We Need an Introduction?

The key aim of the introduction is to introduce to the reader the purpose of your research. Just imagine any academic writing starting from the main body section. You cannot pour on the reader your evidence, ideas, and arguments without an explanation of what are you writing about. In the introduction, you must clearly indicate the hypothesis you want to prove or deny. You must explain the necessity of your research, its urgency, and significance for your study, and, finally, hook readers to continue reading it!

What Information Can I Get From my Search for the Introduction?

It depends on the discipline you are writing the research paper on. If your field of study is Humanities, it is likely that you can find a relevant quote, aphorism, or anecdote to introduce your topic to the reader. In case you study tech, social, and medical sciences quotes are irrelevant. More precise and specific facts will fit such an introduction. There is a general rule for all specialties too. You must find a fact that will intrigue a reader. You must hook him.

Attract the Reader in Any Case

Imagine that your research paper is a product that you want to sell and be paid for it. Figuratively, it is true because your aim is to be rewarded with high mark. The first thing salesmen do to sell their product is a promotion of it. They put effort into and use various methods to hook clients. So, what should research paper writers  do to attract a reader? Even if you write a research paper, and the style of writing is formal, it is still necessary and possible to draw his attention. For example, your research paper topic is “How has the music industry been affected by the internet and digital downloading?”. After a hasty internet search, you can find out that there are many legendary musicians like Radiohead that gave up being dependent on music labels and started to issue their LPs by themselves, online. Also, there is a site Pledge Music which is a popular crowdfunding platform for modern musicians. Such popular synth-pop band as IAMX raises money there to record and promote their albums. These two facts prove that digital downloading somehow affects the music industry, and it is urgent to research this topic to learn the character of this effect. Connect with a professional writer in 5 simple steps. Start now Please provide as many details about your writing struggle as possible. Next What's the area of study of your paper?

Writing a Thesis Statement

Research paper writing is one of the most challenging tasks for students. To write your research papers in a relevant way, it is important to add new information and to connect the text with the research topic. For example, a research paper introduction example can help you learn how to create an introduction that grabs the attention of the reader. The introduction should not only explain the topic but should also provide enough detail to set up the body of the paper. This can be done by providing background information, presenting a hypothesis, or discussing existing research on the topic. Adding new information will make the introduction more interesting and will lead the reader to the body of the paper.

What do you feel when you watch a good teaser for the movie? You feel hooked, intrigued, and eager to watch the story till the end. The same result you must achieve with the thesis statement in a research paper. You must indicate the highlights of your essay, and leave an open question, a mystery, which the reader will want to learn for sure. To provide a worthy example of a research paper thesis statement let’s return to the discussed above topic “How has the music industry been affected by the internet and digital downloading?”. A thesis statement is a point that you will have to defend. It mandatorily must not be general. For example, if you declare this statement during the conversation, it will surely provoke a conflict and make all people differ in their attitude and take a side. Wrong way: “Downloading music from the internet is bad and we must fight it.” It leaves too many questions to answer. And this statement is way too objective, it does not reflect the controversy of your topic. The truth is that there are no absolutely good or totally bad phenomena. And your thesis statement must show the reality.

Right way: “The culture of digital music consumption must be changed because the creations of musicians become worthless due to activity of web pirates and people stop valuing music according to its merit .”

In this example of thesis, I’ve narrowed my argument to the consequences of digital music downloads on the culture of music consumption. I’ve also focused on the fact that the main harm to the music industry present web pirates.  It induces readers to assume that I will argue against them in the main body. To check if you have created a debatable thesis statement for the research paper, you must figure out whether it is debatable. It means that you must make the reader argue either for or against this statement. Wrong way : “The music industry has changed because of the era of the internet.” It is a statement, but not a thesis statement. It is a general truth. There is no point to argue with that fact. You can narrate about that, but not argue and make research to provide proper evidence to prove your point.

Right way: “Free music download sites must become commercial because recording a music is a full-time job of musicians and every work must be rewarded.” Now it is debatable. Opponents can argue that product that music product is not principal way to earn money for musicians, and internet is a the most effective way to promote their creation and lure audience to visit their concerts, what is a real way to earn money.

Research paper Introduction Writing Tips

Research paper introduction is an essential part of your writing and it must be created according to certain rules. It is true that when you write any kind of text you can push yourself too hard and cross the borders of norms. Because academic styles of writing are referred to as creative writing as well. You look for information, then analyze it, come up with thoughts, and ideas, and reflect it in a coherent text. The next tips will show you how to fulfill the purpose of the research paper introduction and get rid of the creative mess.

• Size matters. Before a tutor starts reading the article, he reviews it visually. If the size of the introduction is too large, it will make a bad impression on your paper. Just remember, all you have to present in the introduction is: the definition of the topic idea and its urgency, an explanation of the aim of the research, facts to hook the reader, and a thesis statement.
• Be logical. Your introduction will be really strong if it contains key ideas only in a few sentences. To reach such a result it is important to satisfy the logical connection of the thoughts. Your goal is to make the reader understand in the end of the introduction what exactly you attempted to achieve in a research paper and why this problem is worth profound research.
• Make it the last part. Many successful students first work on the whole outline, write the body of the paper and only then form the introduction. That’s because a person becomes more sure in what direction his research goes only after at least a shallow search and analysis of sources.
• Review previous studies on your topic. Every person can study the same topic in a different way. Before you start your own research, you must become aware of the discoveries other scholars made on this issue. Any result will be a reliable background for future work. Note that it is better to indicate recent developments in the primary research rather than a lengthy report.

Research Paper Introduction Example

Finally, when we have analyzed all highlights of introduction writing we can gather all parts of it in one, ultimate part of a paper. Let’s refresh the exemplary topic of it:  “How has the music industry been affected by the internet and digital downloading?”. Now, have a look at the research paper introduction example: “The musical marketing turns to be digital according to demands of current online epoche. Such underground, but worldwide famous bands like Radiohead and IAMX gain profit from the internet and use it as a primary source to show the audience their creation. On the other hand, many artists find the digital era harmful and destructive to their creativity because there are many sites that offer their products for free, giving no profit to the creator. Currently, there are more and more studies that reveal the business side of the music industry is far from the positive side. This research paper will define whether the culture of digital music consumption must be changed because the creations of musicians become worthless due to the activity of web pirates and because people have stopped valuing music according to its merit.”

As you see, all main components are preserved in the example above. The first sentences hook readers, the mid part of the introduction prove the reason for the research, and the thesis statement puts a debatable argument that needs further analysis and the right solution.

Integrity is a Key

After you created the final paper, be decisive to make necessary changes and corrections, especially before the submission. It usually happens that at the end of the research, a writer can face with inconsistencies in all sections of his writing. If the whole paper does not sound like a cohesive text, make improvements. If your main part does not answer the question raised in the introduction nothing obstructs you from adjusting its sense to the ideas from the main body. A paper with cohesive text deserves a high mark, so rule your writing!

Now You’re a Winner

I suppose that before you came across this article you underestimated the value of a worthy introductive paragraph. In fact, I have not introduced you to another meaningful feature of it. You know that all academic essays must end with a conclusive paragraph. There is an assumption that this is the hardest part of research paper completion. In fact, if you have succeeded in making of impressive introduction, you will significantly facilitate the process of conclusion writing. You don’t think it is easy for you? Ask professionals “ write an essay for me ” because writing your essay does not have to be a difficult job.

This research study is performed on the self-compacting geopolymer concrete (SCGC) combining coal bottom ash (CBA) and metakaolin (MK) as a substitution for GGBFS alone and combined for analysing the fresh properties (slump flow, V-Funnel, and T50 flow), mechanical characteristics (compressive, splitting tensile and flexural strengths) and durability tests (permeability and sulfate attack test). Though, total 195 SCGC samples were made and tested for 28 days. It has been revealed that the consumption of CBA and MK as a substitution for GGBFS alone and combine in the production of SCGC is decreased the workability of SCGC while mechanical characteristics of SCGC are enhanced by utilizing CBA and MK as a substitution for GGBFS alone and combine up to 10%. In addition, the compressive, splitting tensile and flexural strengths were calculated by 59.40 MPa, 5.68 MPa, and 6.12 MPa while using the 5CBA5MK as a substitution for GGBFS in the production of SCGC after 28 days correspondingly. Furthermore, the permeability is decreased by growing the quantity of CBA and MK by the weight of GGBFS alone and jointly in the production of SCGC after 28 days. Besides, the minimum change in length of the SCGC specimen is recorded by 0.062 mm at 7.5MK7.5CBA while the maximum change in length is calculated by 0.11 mm at 10CBA10MK as a substitution for GGBFS at 180 days correspondingly. In addition, the embodied carbon is recorded reduce as the addition of CBA while it is getting higher when the accumulation of MK alone or combined with CBA in SCGC. Besides, response models for prediction were constructed and confirmed using ANOVA at an accuracy rate of 95%. The models' R 2 fluctuated from 88 to 99%. It has been observed that the utilization of CBA and MK alone and together up to 10% as substitution for GGBFS in geopolymer concrete provides the best results therefore it is suggested for structural applications.

Introduction

Concrete is frequently employed in construction applications throughout the globe 1 . Portland cement (PC) is an imperative component of concrete, and it is not universally sustainable. Sustainability issues associated with Portland cement production are well-known. Portland cement production discharges large quantities of carbon dioxide (CO 2 ) and additional dangerous gases into the environment due to the mechanism of decarbonation of limestone and the burning of energy sources such as fossil fuels. 1 tonne of PC needs approximately 1.6 tonnes of raw materials and 6.5 million British thermal units of energy, resulting in the release of 1 tonne of CO 2 into the natural environment 2 , 3 , 4 .

Globally, the PC industry releases about 1.65 billion tonnes of global warming annually, contributing to about 7% of global CO 2 emissions 5 , 6 , 7 , 8 . The CO 2 production from the manufacture of PC is projected to increase by approximately 50% from existing levels by 2050 9 , 10 . To protect the environmental issues from the impacts of PC production, new options for producing a more economical and environmentally friendly concrete material to substitute standard PC concrete must be identified and evaluated 11 . To resolve global warming concerns, enormous initiatives have been made to minimize the usage of PC on a global scale. Among these are the recycling of waste by-products and the production of PC replacements 12 .

Geopolymer concrete (GC) is a significant advancement in unique product development, resulting in an economical, environmentally acceptable constituent that can be used in place of PC 12 , 13 , 14 , 15 . It is an alumino-silicate-based synthetic polymer concrete that can be produced in a strong alkaline solvent using silicon and aluminum-rich geological elements or by-product constituents 16 . The GC is invented by substituting the PC entirely 17 , 18 , 19 , 20 , 21 . Apart from PC, the manufacturing of natural components for geopolymers are not necessarily involve a lot of energy consumption. The binder used in geopolymer has been proven to discharge between a 5th to 6th of the Carbon dioxide generated by Portland cement 22 . As a result, geopolymer concrete not only minimizes CO 2 production associated with the PC sector, and waste materials residues of alumino—silicate concentration are also used to make high-performance constituents for construction 23 , 24 .

Moreover, GGBFS is obtained through the collection of waste components from a particular industry, namely metallurgical. The slag is produced in the form of molten iron, which is formed when a mixture of components such as coke, iron ore, and limestone is heated to between 15,000 and 16,000 degrees Celsius. The resulting slag has a chemical structure alike to PC, with approximately 45% CaO and 35–45% silicon dioxide. Additionally, glassy particles are formed when silicon-aluminum slag is rapidly immersed in liquid form after molten iron is removed 25 , 26 , 27 , 28 . Dewatering and converting such glassy particles to the desired size 29 , 30 . This crushed slag is referred to as GGBFS, and because it is an environmentally friendly building material, which can be utilized in place of PC in concrete, thereby reducing carbon dioxide production and PC use in the construction industry 31 . GGBFS can enhance durability assets, resistance to corrosion, and sulfate resistance. By considering these properties, it is feasible to prolong the infrastructure life and reduces maintenance budgets. Due to the high concentration of GGBFS in the eco-friendly circumstances utilized to substitute cement, concrete not only recycles waste but also conserves natural assets and reduces energy utilization 32 , 33 . As a consequence, GGBFS was preferred as the starting material for geopolymer synthesis in this investigation to maximize the utilization of this industrial waste and to produce geopolymer concrete based on GGBFS.

The enhancement of concrete construction throughout the last 2 decades has increased focus on improving efficiency and striving to improve the effective atmosphere. Self-compacting concrete (SCC) is a comparatively novel improvement in the field of concrete production which is gaining traction. Distinct from conventional concrete, SCC has the capability to flow through and around obstacles by itself, completely covering the formwork and self-compacting without segregation or blocking 34 . It has a variety of technical, economic, and ecologic benefits over existing concrete, like enhanced concrete quality, decreased duration of construction, relatively easy installation in clogged reinforcement, and consolidation completion, enhanced bond strength, reduced overall costs, and a quieter working environment due to the absence of vibration 35 , 36 , 37 . This results in a reduction in the presence of guidance from a professional, along with a decreased tolerance for pictorial errors, excessive noise, and workplace injury. The essential components in the production of SCC are the same to plane concrete, with the exception that SCC is composed of a variety of different percentages and supplementary mineral admixtures blends. SCC mixtures typically contain a larger quantity of ultra-fine constituents. SCC has superior flowability owing to its lesser concentration of coarse aggregates, lesser water/binder ratio, and utilization of superplasticizers and viscosity-modifying agents 38 , 39 . The cement substitution ingredients are extensively utilized to decrease costs and increase the performance of fresh and hardened concrete 40 , 41 . The usage of SCMs like groundnut shell ash (GSA), GGBFS, fly ash (FA), coconut shell ash (CSA), millet husk ash (MHA), and silica fume (SF) is well recognized for improving concrete properties and for environmental and economic reasons 34 .

Metakaolin (MK) is created by burning kaolin clay at temperatures fluctuating from 650 to 800 °C. It has possessed the pozzolanic property, therefore, MK can be used as a SCM in concrete, and when it is mixed in concrete as cementitious material that improves the ITZ of concrete compared to other ingredients which results in improving the strength 42 . For decades, MK has been utilized commercially in construction sector 43 . The majority of studies used concrete containing MK as supplementary cementitious material (SCM), showing a notable enhancement in the mechanical characteristics. Poon et al. 44 performed research work on MK as SCM in concrete which enhanced the mixture’s mechanical properties while decreasing its porosity. It has been realized that by using MK dosages enhanced in concrete, pore spaces are minimized. Jin and Li 45 explained an associated tendency. Ahmed et al., 46 stated that the consumption of MK up to 15% in matrix increases crushing and flexural strength. The majority of prior investigation has focused on using MK in geopolymers mixture 47 , 48 . MK is a crucial strategy for reducing the carbon footprint of concrete 47 , 48 .

Moreover, the CBA is produced when coal is burned in thermal power plants which is the primary waste product of fly ash (FA). Owing to the existence of SiO 2 , Fe 2 O 3 , and Al 2 O 3 in the CBA, it possesses pozzolanic properties. The calcium hydroxide reacts with calcium aluminate hydrate (CAH) throughout cement hydration to form supplementary CAH and calcium silicate hydrate (CSH) 49 . According to prior research 49 , suitable crushing can enhance the CBA pozzolanic activity, and six hrs of crushing CBA can result in a 27% growth in strength. As a result, it is partially substituted in concrete by FA and PC 50 . CBA usage in building sector is one of the most effective ways to mitigate environmental issues due to a lack of discharge sources and augmented CBA production. India generates almost 105 million metric tons of CBA every year for many thermal power plants, which provide 68% of the nation’s energy production. The inclusion of CBA in the current and future building industries is being advocated for owing to its comparable particle size distribution and supplementary pozzolanic characteristics to NFA 49 .

Furthermore, based on the literature study, there are no experimental investigations performed on SCGC mix inclusion with MK and CBA as a substitution for GGBFS individually and combine. Therefore, this study examined the fresh properties, mechanical properties, durability properties and embodied carbon of GGBFS-based SCGC inclusion with MK and CBA as a substitution for GGBFS. The outcomes demonstrate a noteworthy enhancement in the strength properties of GGBFS-based SCGC blended with MK and CBA separate and combined and these materials can be advantageously utilized in the production of SCGC mixture by applying response surface methodology (RSM) tool for modelling and optimization.

Concept of the geopolymerization mechanism

The concept of the geopolymerization mechanism is fundamental to understanding the formation and performance of SCGC with MK and CBA as substitutions for GGBFS. Geopolymerization is a complicated chemical process that starts with aluminosilicate materials dissolving in an alkaline solution 51 . The ions that are dissolved then condense into a stable network of three-dimensional tetrahedral structures 52 , 53 . The reaction of the alumina and silica available in the constituents (like MK and CBA) with the alkaline activator (in this case, sodium carbonate) drives this process. The resulting geopolymer matrix is composed of interconnected Si–O–Al bonds, forming a rigid, stable structure that contributes to the material’s mechanical strength and durability 54 , 55 , 56 , 57 .

The inclusion of MK and CBA in the SCGC affects the geopolymerization process and the final microstructure. Metakaolin, because of its high reactivity and small particle size, easily dissolves in alkaline conditions, delivering a plentiful supply of reactive alumina and silica. This promotes the creation of aluminosilicate gels, which are essential for the construction of the tetrahedral network 58 . While CBA has lower reactivity than MK, it plays a role in the overall matrix by occupying empty spaces and decreasing porosity, potentially enhancing the strength and longevity of the geopolymer concrete. The synergistic impact of MK and CBA results in a more condensed and tightly packed microstructure, characterised by a well-established tetrahedral network that exhibits high resistance to environmental factors such as water and sulfates 58 .

The geopolymerization mechanism clarifies the several steps involved in the geopolymerization process, starting with the initial dissolution of aluminosilicate minerals and culminating in the production and expansion of the tetrahedral network 59 , 60 . Additionally, it might elucidate how the distinctive attributes of MK and CBA contribute to this procedure and how the fine-tuning of their proportions impacts the overall efficacy of the SCGC. This feature would enhance readers' comprehension of the development of the material’s microstructure and its correlation with the observed mechanical characteristics and durability by offering a clear and comprehensive explanation of the underlying processes. Gaining a more profound comprehension of this subject matter will not only enhance the present investigation but also provide direction for future investigations and actual implementations in the realm of sustainable construction.

Experimental program

The GGBFS was obtained with permission from the steel mill and thereafter dried for 24 h in the open environment. After sieving the dried GGBFS from a 75 µm mesh to disregard any undesired particles, it is applied as a binding constituent in SCGC. However, in this investigational study, metakaolin (MK) served as a substitution for GGBFS in the production of SCGC. It was obtained and then dried for 24 h under the environment before being sieved from a 75 µm mesh to disregard unwanted constituents and then it was utilized in SCGC as a substitute for GGBFS material. Additionally, coal bottom ash (CBA) was stored with permission from the Coal Power Plant. After collecting the CBA, it was dried for 24 h at 105 °C and then allowed to pass from a 75 µm mesh to disregard bulky particles. Sieved ash was then utilized in place of GGBFS in the production of SCGC. Table 1 summarises the chemical configurations of GGBFS, MK, and CBA. Furthermore, both the manufacturing of geopolymers is needed to absorb alumina, and silica, and the polymerization catalyst procedure, which is required for an alkaline solution 61 . This research was using an alkaline liquid composed of sodium silicate (SS) and sodium hydroxide (SH). For this experimental investigation, SH and SS solutions were used. To prepare an SH solution, dissolve SH particles in enough drinkable water to reach the desired concentrations and left the solution for 24 h to cool down. Besides, to develop an alkaline solution by combining the two aqueous mixtures. Additionally, the superplasticizer (SP) is added for increasing the fresh property which is to the level needed for SCGC mixture compliance with the EFNARC 36 code procedure. Additionally, in this investigational study, drinking water was provided to create the alkaline solution. In addition, the coarse aggregates (CA) with a 12 mm particle size and fine aggregates (FA) with possess 4.75 mm in size were applied for this study.

Mix proportions

This experimental procedure was adopted to thirteen SCGC mixes, one of which was composed entirely of GGBFS as a binding material, four of which contained 5–20% GGBFS replaced with MK, four of which contained 5–20% CBA as a substitution for GGBFS, and four of which contained a combination of MK and CBA as a replacement for GGBFS. All SCGC mixes are examined in this investigational study, as seen in Table 2 . Though, to generate a homogeneous mixture, dry materials such as GGBFS, MK, CBA, and aggregates are mixed in a concrete mixer for approximately 2.50 min in the dry state, monitored by the accumulation of a well-shaken premixed solution combination comprising an alkaline solution, SP, and additional water for three minutes. The SCGC mixture was characterized after the homogeneous SCGC mixture was examined for key tests on workability such as slump flow, V-Funnel, and T 50 flow. After checking the SCGC mixture’s workability, it was placed without compaction into steel moulds (cubes, cylinders, and prisms), entirely occupying all gaps in the moulds with self-weight of mixtures. In addition, cubical samples were cast to analyse the compressive strength, cylinders to determine the indirect tensile strength, and beam samples were prepared to perform the flexural strength. Furthermore, concrete samples were cast to determine the permeability and sulfate attack test of SCGC.

Testing methods

Workability of scgc.

It was accomplished in terms of slump flow, V-Funnel, and T 50 flow blended with several extents of MK and CBA as a substitution for GGBFS separately and in combination were determined utilizing EFNARC’s European self-compacting concrete guidelines 36 .

Mechanical properties of SCGC

The cubical samples made of SCGC inclusion of MK and CBA as a substitution for GGBFS were cast for compressive strength while the cylindrical samples of SCGC addition with MK and CBA as a substitution for GGBFS were tested for splitting tensile strength by obeying the BS EN 12390-3 67 and BS EN 12390-6 68 code procedure at 28 days consistently. In the same way, the prism specimens made of SCGC mixture introduction of MK and CBA as a substitution for GGBFS were prepared for analysing the flexural strength by obeying the BS EN 12390-5 69 code standard.

Durability of SCGC mixture

The permeability was performed on the concrete samples made of SCGC inclusion with MK and CBA as a substitution for GGBFS by using BS EN-12390-8 70 code procedure while the sulfate attack test was executed on the prism samples made of SCGC incorporating CBA and MK as a substitution for GGBFS and length change of samples was evaluated by using the ASTM C 1012-04 71 code procedure at 180 days.

Results and discussions

Fresh properties.

It is employed for assessing the workability of SCGC production accumulation with CBA and MK as a substitution for GGBFS alone and combined as shown in Fig.  1 . According to the EFNARC 36 , the slump flow is lying between 650 and 850 mm for all fresh mixes of SCGC. However, the highest slump flow is measured by 752 mm in the SCGC mixture which is made of GGBFS only while the lowest value is measured by 582 mm at 20% of GGBFS replaced with MK in the production of SCGC. It has been noted that as the amount of MK as a substitution for GGBFS grows in SCGC is decreased the slump flow. This finding is related to Arun et al., 72 where the workability of mix decreases but MK increases. Bheel et al., 2 reported that the usage of FA replaced with MK rises in the production of SCGC reducing the slump flow. A similar kind of study was done by Guneyisi and Gesoglu 73 . In the same way, the maximum slump flow is predicted to be 695 mm at 5% CBA, while the lowest value is projected to be 550 mm with 20% of CBA substituted with GGBFS in the production of SCGC. The addition of CBA to SCGC decreases the slump flow. This trend has been executed by Bheel et al., 3 that the slump flow is declined as content of WSA as a substitution for MK rises in SCGC. Furthermore, the CM has the highest slump flow of 752 mm, while the smallest value is noted by 578 mm at 10MK10CBA as a replacement for GGBFS in the production of SCGC. The combined amount of MK and CBA used to replace GGBFS rises in SCGC declined the slump flow. The greater specific surface area of MK and CBA which absorbs more water, leading to a drop in slump flow, and resulting in a stiffer mix. In real-world construction scenarios, a significant amount of MK may require the incorporation of superplasticizers to ensure the material remains flowable, as it tends to have a reduced slump flow. On the other hand, a higher amount of CBA can result in decreased workability, making it more difficult to place the material in complicated formwork or heavily reinforced portions. Although MK improves the material’s mechanical characteristics and durability by virtue of its pozzolanic reactivity, CBA may also make a significant contribution to the material’s strength and durability at an early stage. Local availability, affordability, and sustainability factors may also impact the selection between MK, CBA, and GGBFS. CBA, being an industrial by-product, is often more affordable and easily accessible, hence aiding waste management efforts as well as decreasing the carbon footprint associated with concrete manufacturing. Conversely, because MK is a manufactured material, it has a higher level of embodied energy. Thus, in order to meet the demands of structural purposes that require exceptional strength and durability, it may be more advantageous to use a mixture with a higher percentage of GGBFS and MK, even if it results in lower workability. On the other hand, for non-structural purposes where workability is of utmost importance, it is essential to carefully control the quantities of CBA. Ensuring a proper balance of these elements is crucial for optimising the mix design of SCGC to meet particular building requirements. This assertion is connected to Guneyisi and Gesoglu 73 , who discovered that slump flow reduces while MK rises in the SCC. Bheel et al., 3 conveyed that the accumulation of WSA and Millet husk ash (MHA) as a substitution for MK increases in the production of SCGC is reduced the slump flow. A similar kind of trend was perceived by Memon et al., 74 , and Bheel et al., 2 .

Slump flow of GGBFS-Based SCGC.

V-funnel test

It was executed to measure the workability of SCGC addition with MK and CBA as a substitute for GGBFS alone and combined in the production of SCGC as revealed in Fig.  2 . The flow time of the fresh mix is documented during the experiments. Based on the experimental outcome, the V-funnel flow time is lying in ranges from 8.40 to 13.10 s when various amounts of MK and CBA are used to substitute GGBFS separately and combined in the SCGC combination. Except for MK15, MK20, CBA20, 7.5CBA7.5MK, and 10CBA10MK, the V-funnel flow time of the remaining nine SCGC combinations accomplishes the requirement for a desirable V-funnel flow time. The minimal V-funnel flow duration is 8.40 s for SCGC without the accumulation of CBA and MK as substitutes for GGBFS alone and jointly. As shown in Fig.  2 , the V-funnel flow time is improved as the content of MK and CBA as a substitute for GGBFS separate and together rises, which cause the decrease in the flow of SCGC. This decrease in V-funnel flow time is owing to the extremely small particle size of MK and CBA, which increases their specific surface area relative to GGBFS. The presence of varying amounts of MK and CBA in the V-Funnel test for SCGC has a notable impact on the flow time. This suggests that the viscosity of the mixture and the possibility of segregation are altered. Greater concentrations of MK, as a consequence of its elevated reactivity and small particle size, often lead to longer flow times, suggesting heightened viscosity and a more viscous mixture. The heightened viscosity contributes to a decrease in the likelihood of segregation, guaranteeing a more consistent and stable mixture. Conversely, adding more CBA often leads to longer flow times. This is because the irregular shape and larger size of CBA particles increase internal friction, as well as the viscosity of the mixture. Nevertheless, an overabundance of CBA may also result in workability problems and possible segregation if it is not well balanced with other constituents. In general, adding both MK and CBA in the right quantities may improve SCGC’s stability by increasing viscosity and decreasing segregation. However, it is important to carefully analyse the amounts of these additives to ensure that the ideal flow features and workability of the concrete mix are maintained. Bheel et al., 3 presented that the V-funnel flow time of fresh mixture is decreased as the quantity of WSA and MHA as a substitution for MK separate and together rises in the production of SCGC. A comparable investigation was conducted by Memon et al. 75 , Dhiyaneshwaran et al. 76 , and Bheel et al. 2 .

V-Funnel Flow of GGBFS-Based SCGC.

Figure  3 illustrates the T 50 flow assessment, which is executed to check the flow of mixture of SCGC production qualities, comprising the use of MK and CBA as a substitute for GGBFS. For this test, the slump flow time should be attained to 50 cm in diameter when performing the fresh mix of SCGC. It has been observed from the experimental outcome that the slump flow time of fresh mixture is lying in the ranges from 2.8 to 6.15 s when MK and CBA are used in varying quantities to replace GGBFS separately and combined in SCGC mixture. According to EFNARC 36 , the slump flow time is noted within the acceptable range (2–5 s) for all SCGC combinations except MK15, MK20, CBA15, CBA20, and 10CBA10MK. The minimum slump flow time of 2.80 s is observed at the SCGC mixture without the accumulation of CBA and MK as substitutes for GGBFS separately and in combination. As illustrated in Fig.  3 , the slump flow time of SCGC improves as the proportion of MK and CBA used to replace GGBFS alone and jointly increases in the production of SCGC. This increase in the T 50 flow time is attributable to the increased paste volume achieved by using MK and CBA in place of GGBFS alone and together in SCGC. Moreover, the T50 time characteristic provides information about the concrete mixture’s viscosity and flow properties. A shorter T50 time implies lower viscosity and improved flowability, while a longer T50 time predicts greater viscosity and decreased workability. Using MK and CBA separately as GGBFS substitutes tends to increase the T50 flow time. MK, owing to its pronounced reactivity and the presence of small particles, substantially elevates the viscosity and diminishes the flowability. Likewise, CBA, because of its irregular and bigger particles, causes a rise in internal friction, resulting in increased viscosity and longer T50 times. The combined influence of MK and CBA on the T50 flow time is cumulative, leading to a mixture with increased viscosity and extended T50 durations. Using this combined substitution may improve the stability of the concrete mix while reducing the danger of segregation. However, it is important to carefully balance the proportions to ensure that the workability of the mix remains sufficient. Therefore, whereas each material alone enhances the T50 flow time, their combined use necessitates optimisation to maximise their advantages while balancing the compromise in flowability. Bheel et al., 2 itemized that the T 50 flow time is amplified by inclusion the content of Groundnut shell ash and MK by the weight of FA alone and together rises in the production of SCGC. The analogous trend was perceived in Memon et al. 75 , Bheel et al., 3 , Keerio et al., 65 , and Dhiyaneshwaran et al. 76 .

T 50 Flow of GGBFS-Based SCGC.

Mechanical properties

Compressive strength (cs).

The CS of SCGC containing CBA and MK as substitutes for GGBFS is measured in Fig.  4 . Nevertheless, the compressive strength is 57.40 MPa, 59.86 MPa, and 57.10 MPa at 5%, 10%, and 15% of GGBFS substituted with MK, respectively, which is more than CM, and thus the strength of SCGC mixture is reached. After 28 days, 52.50 MPa at 20% MK as a substitution for GGBFS is less than SCGC prepared with GGBFS as the only binding agent in the mixture. It has been detected that the accumulation of 5–15% of MK as a substitution for GGBFS in the production of SCGC is increased the CS, however, increasing the amount of MK as a GGBFS substitution ingredient in SCGC decreases the strength. Additionally, the CS is optimized at 56.80 MPa, 58.76 MPa, and 56.40 MPa when 5%, 10%, and 15% of GGBFS are substituted with CBA, correspondingly, while the minimum strength is seen at 51.25 MPa when 20% of GGBFS is substituted with CBA after 28 days. The outcomes indicate that using CBA as a substitute for GGBFS augmented the CS of the SCGC combination up to a point where it begins to drop. This aspect is correlated to Memon et al., 75 , who demonstrated an increase in the crushing strength of SCGC by substituting SF for FA up to 15% in the combination at 28 days. Furthermore, the highest CS is 57.25 MPa, 59.40 MPa, and 56.98 MPa at 2.5CBA2.5MK, 5CBA5MK, and 7.5CBA7.5MK, consecutively, while the minimum CS is 52.20 MPa at 10CBA10MK as a substitution for GGBFS in the production of SCGC after 28 days. It has been perceived that the use of CBA and MK up to 15% as a substitution for GGBFS combined in the production of SCGC is increased the CS. This enhancement in strength is related to the extremely small size of CBA and MK particles in comparison to GGBFS, which makes the pores smaller and the particles more densely packed, producing the concrete denser and more stable. Bheel et al., 3 described that the 10% of MK substituted with WSA and MHA combined in SCGC augmented the CS. A similar observation was done by Keerio et al. 65 and Bheel et al., 2 .

CS of GGBFS-based SCGC.

Splitting tensile strength (STS)

It was achieved on SCGC specimens’ addition with MK and CBA as a substitution for GGBFS alone and jointly after 28 days as directed in Fig.  5 . The highest STS is noted by 5.75 MPa and 5.63 MPa when using 10% of MK and CBA as a substitution for GGBFS, while the least strength is measured by 5.18 MPa and 5.0 MPa at 20% of CBA and CBA as a substitution for GGBFS in the production of SCGC after 28 days consistently. The experimental result has shown that the STS is enhanced when the usage of CBA and MK up to 15% as a substitution for GGBFS alone and further addition of CBA and MK in the SCGC, the STS gets declined. Bheel et al., 2 assured that the accumulation of 10% FA substituted with MK in the production of SCGC boosted the STS at 28 days. Memon et al., 75 notified that the usage of 10% of FA replaced with SF in the production of SCGC augmented the STS after 28 days. Moreover, the greatest STS is estimated by 5.68 MPa at 5CBA5MK and the lowest strength is 5.12 MPa at 10CBA10MK as a substitution for GGBFS in the production of SCGC on 28 days correspondingly. From Fig.  5 , it has been shown that the consumption of MK and CBA combined up to 15% as a substitution for GGBFS boosted the STS of SCGC. This enhancement in strength is associated with the MK and CBA possessing a higher specific surface area as compared to GGBFS in the production of SCGC. A analogous study was performed by Bheel et al. 2 , where the STS of SCGC is augmented when the consumption of MK and GSA combined up to 10% as a substitution for FA after 28 days. Similar kinds of findings were observed in 3 , 65 , 72 , 76 .

STS of GGBFS-based SCGC.

Flexural strength (FS)

It was performed on the prism samples made of SCGC introduction of MK and CBA as a substitution for GGBFS alone and together for 28 days as exhibited in Fig.  6 . The optimal flexural strength is measured by 6.20 MPa at 10% of MK while the least flexural strength is recorded by 5.50 MPa at 20% of MK as a substitution for GGBFS in the production of SCGC on 28 days, consistently. The result has shown that the FS is enhanced when the usage of MK as a substitution for GGBFS alone up to 15% and more accumulation of MK in the SCGC, the strength starts declined. In the same way, the optimum flexural strength is computed by 6.0 MPa when the consumption of 10% CBA as a substitution for GGBFS and the minimum value is seen by 5.35 MPa at 20% GGBFS replacement with CBA after 28 days consistently. The assessment results demonstrated that the using of CBA as a substitution for GGBFS to 15% in the production of SCGC increased the flexural strength, and after 15% of CBA, it begins to deteriorate. The finding of the experimental was provided by Bheel et al. 2 , wherever the usage of 10% FA as substituted with MK in the production of SCGC augmented the flexural strength for 28 days. Bheel et al. 3 declared that the accumulation of 10% WSA as a substitution for MK in the production of SCGC enhanced flexural strength at 28 days. A comparable finding was done by Memon et al., 75 . Furthermore, the greatest flexural strength is estimated by 6.12 MPa at 5CBA5MK while the minimum strength is acquired by 5.42 MPa at 10CBA10MK as a substitution for GGBFS in SCGC on 28 days consistently. The outcome has been discovered that using CBA and MK as combination material substituted with GGBFS up to 15% in the production of SCGC improved the FS. The increased FS is related with the very fineness of CBA and MK particles, which plugs the voids produced by water in the production of the SCGC matrix. The usage of MK and CBA as the finer particles decrease the microcracks in SCGC and generate a significantly denser SCGC that results in improving the strength of the concrete 77 . Bheel et al. 2 described that the combined consumption of 10% FA substituted with GSA and MK augmented the FS of SCGC at 28 days. The comparable findings were carried out by 3 , 65 , 72 , 73 , 78 .

Durability of SCGC

Permeability of scgc.

It was executed on the SCGC samples incorporating CBA and MK as a substitution for GGBFS alone and jointly at 28 days as indicated in Fig.  7 . The permeability of SCGC was assessed by 20 mm, 17 mm, 14 mm, and 10 mm at 5%, 10%, 15%, and 20% of GGBFS substituted with MK at 28 days, correspondingly. The permeability is decreased when the amount of MK as a substitution for GGBFS grows in the production of SCGC. According to Keerio et al., 64 , the permeability is lowered by up to 15% when MK is used as a substitution for cement for 28 days. The comparable findings were provided by Bheel et al. 79 . Furthermore, the permeability of SCGC is calculated by 22 mm, 19 mm, 16 mm, and 12 mm at 5%, 10%, 15%, and 20% of GGBFS substituted by CBA at 28 days, correspondingly. As the extent of CBA as a substitution for GGBFS in SCGC rises, the permeability of the SCGC decreases. Guneyisi et al. 80 carried out a similar study in which the permeability decreased as the MK extent of concrete increases. Furthermore, the permeability of the SCGC is calculated by 21 mm, 18 mm, 15 mm, and 11 mm at 2.5CBA2.5MK, 5CBA5MK, 7.5CBA7.5MK, and 10CBA10MK as a substitute for GGBFS after 28 days is smaller as compared to SCGC without the presence of CBA and MK. According to Fig.  7 , the permeability is decreased, while the content of CBA and MK combined as a substitution for GGBFS rises in the production of SCGC. The water penetration depth in SCGC specimens with MK and CBA substitutes for GGBFS, as determined by BS EN 12390-8, offers important information on the long-term durability and permeability of the concrete. A lower water penetration depth usually suggests a more compact and less porous concrete structure, which is directly linked to improved durability. The replacement of GGBFS with MK and CBA might have an impact on the microstructural properties of the concrete. Because of its small particle size and strong reactivity, MK may fill empty spaces and aid in the creation of more gel-like substances, thereby decreasing the concrete’s porosity and permeability. When appropriately treated, CBA may also function as a filler substance, resulting in a further reduction in pore volume and enhancing the overall density of the matrix. These changes in the microstructure result in a concrete that is more resistant to water penetration, which is critical for ensuring its long-term durability. Decreased water infiltration results in a lower vulnerability to phenomena such as freeze–thaw cycles, chloride ion intrusion, and other types of chemical attack. These processes may gradually weaken the structural integrity of the concrete. Hence, the water penetration test’s depth, as specified in BS EN 12390-8 70 , acts as a vital indicator of the concrete’s performance in hostile surroundings. The correlation between total permeability and the ability of the SCGC with MK and CBA substitutes to survive environmental stressors and preserve its structural integrity over a long period of time is evident. Existing research supports this association, highlighting the significance of low permeability in the construction of long-lasting concrete buildings. Bheel et al. 79 did related work in which the permeability is reduced when the doses of combined GGBFS and MK by the mass of cement rise in concrete. A related finding was agreed by Bheel et al. 2 where the usage of FA substituted with GSA and MK increases alone and jointly in the production of SCGC is reduced the permeability at 28 days.

Sulfate attack test

Sulfate attack is one of the main aspects of durability that can be modified by the independent and combined substitution of GGBFS with MK and CBA as shown in Fig.  8 . Sulfates are typically found in water, especially when the soil contains a high amount of clay. The abundance of sulfates in rainwater is likely owing to air pollution and the presence of sulfates in seawater. This sulfate attack test was conducted on prism samples of SCGC combined with MK and CBA as a substitution for GGBFS, and the difference between the beginning and final values is shown in Fig.  8 . However, the change in length of SCGC samples with 5%, 10%, 15%, and 20% substitution of GGBFS with MK and CBA separate and combine owing to sulfate attack is within the acceptable limit (i.e., 0.1% maximum length change) as defined by ASTM for pozzolanic material. Nevertheless, a 15% substitution of GGBFS with MK resulted in the smallest change in length. Sample break-down was not observed in this investigation, which could be attributed to the dense matrix of SCGC, which has a low water-to-binder ratio and a lower specific surface area of metakaolin. Khatib and Wild 81 informed that the integration of MK in composite reduced sulfate attack growth. The concrete comprising 10% or additional MK displayed no expansion, whereas the concrete comprising 0% or 5% MK did not start growing until the age of 180 days 81 . Similarly, at 180 days, a 15% replacement of GGBFS with CBA resulted in the smallest change in length. Specimen breakdown was not observed in this investigation, which could be attributed to the dense matrix of SCGC with a low water-to-binder ratio. According to Sajjad Ali Mangi et al. 82 . The efficacy of concrete including CBA versus concrete with no CBA under 5% sodium sulfate (Na 2 SO 4 ) exposure is similar up to 90 days. For short-term exposure, there is no discernible effect of Na 2 SO 4 solution on concrete with and without CBA 82 . Furthermore, at 180 days, the MK7.5CBA7.5 combined replacement of GGBFS with MK and CBA resulted in the smallest decrease in length. Courard et al. 83 conducted a similar type of study on the sulfate resistance of MK in matrix by using ASTM C 1012. Within a short period of time, the PC mortar prisms exhibit expansion, and the accumulation of 10% MK leads to a 3.7% decrease in expansion compared to CM 83 . According to Kasemchaisiri and Tangtermsirikul 84 , the highest expansion of CM was SCC, followed by SCC-BA 10%, SCC-BA 20%, and SCC-BA 30%, correspondingly. The dense matrix greatly reduced SO4 2- ion migration into the concrete, indicating that increasing bottom ash concentration results in greater sodium sulfate resistance. The pozzolanic reaction of bottom ash reduces this expansion in concrete 85 . Despite their higher porosity, the expansion of SCC with bottom ash (BA) reduces as the BA concentration rises. This suggests that sodium sulfate resistance can be attained by the pozzolanic reaction of BA, which takes precedence over porosity rise. Sulfate resistance improvement is helpful for SCC in sulfate-exposing structures such as underground structures, drilled piles, and undersea structures, among others 85 . Different research 81 , 82 , 83 , 84 , 85 discovered nearly the same trend of sulfate resistance. The ratios of MK and CBA used as GGBFS replacements directly correlate with the extent of length change in SCGC specimens subjected to sulfate attack. Metakaolin, due to its high reactivity and small particle size, aids in the production of a compact and stable geopolymer structure. This structure effectively prevents the penetration of sulphate ions and minimises the development of expansive substances such as ettringite and gypsum. Consequently, an increase in the fraction of MK often results in a decrease in length changes, indicating enhanced resistance to sulfate attack. Moreover, CBA may serve as a substance that fills in gaps, enhancing the structure of the pores and reducing the capacity of sulfate to pass through. The efficacy of CBA depends on its proportions and particle dimensions. It is essential to achieve an appropriate balance between MK and CBA, since an excessive quantity of either might result in negative consequences, such as decreased workability or inadequate geopolymerization. The relationship between material selection and better durability is shown by emphasising the significance of proportioning MK and CBA to produce a geopolymer matrix that is both dense and impermeable. By carefully adjusting the mix’s ingredients, adding the right amount of MK to make sure it has enough pozzolanic activity, and using CBA to increase the toughness, the resulting SCGC may show small changes in length when exposed to sulfate attack. This optimisation guarantees that the concrete retains its structural integrity and durability in situations with high levels of sulphates. Therefore, understanding the relationship between MK and CBA amounts and their impact on the duration change due to sulphate attack is crucial for the creation of long-lasting SCGC combinations.

Sustainability assessment

Embodied carbon (ec).

In order to determine the embodied carbon dioxide emissions associated with GGBFS-based SCGC, an environmental impact assessment is conducted for all aspects pertaining to the combination of different GGBFS replacements with MK and CBA in the combination. Table 3 displays the EC levels for all GGBFS-based SCGC components, sourced from prior research. Equation ( 1 ) 86 is used to determine the EC for all SCGC based on GGBFS. Equation ( 1 ) represents the unit volume weight (kg/m 3 ) and total EC for any GGBFS-based SCGC, denoted by the symbols Ee, CO 2e , Wi, and i. Moreover, the symbols Ei and CO 2i are used to denote the EC content of the physical constituents, as shown in Table 3 .

The study assessed the environmental impact of utilizing GGBFS 98 , 99 , 100 based SCGC mixed with MK and CBA as substitutes for GGBFS by evaluating the EC of each mix. Figure  9 presents the results and compares them to the reference mix. The Fig.  9 illustrates the significant carbon footprint of sodium silicate compared to MK, CBA, GGBFS, CA, FA, SP, SH, and water. Additionally, the embodied carbon of SCGC blended with various GGBFS substitutes, both separate and combined, is shown in Fig.  9 . Furthermore, the figure indicates that sodium silicate emits the high quantity carbon, followed by SH, coarse and fine materials. However, the graph does not show the impact of CBA, SP, and water in the SCGC, suggesting that their contribution to carbon intensity is minimal. Besides, the EC of MK is greater than GGBFS and CBA. Equation ( 1 ) was useful to find out the total of carbon of all SCGC built on the information revealed in Fig.  9 . Figure  9 reveals that the EC of SCGC is recorded by 2.93%, 5.86%, 8.78%, and 11.71% at MK5, MK10, MK15, and MK20 which is greater than that of reference mixture of GGBFS based SCGC at 28 days separately. It has been perceived that the embodied carbon of SCGC is getting higher with accumulation of MK as substitution for GGBFS in SCGC. This enhancement in EC is associated to the EC factor of MK is more than that of GGBFS. Moreover, the EC of SCGC combined with CBA5, CBA10, CBA15, and CBA20 as substitution for GGBFS is calculated by 0.59%, 1.18%, 1.78%, and 2.37% which is lesser than CM of GGBFS based SCGC at 28 days respectively. This reduction in EC of GGBFS based SCGC is owing to the EC factor of CBA is lesser as associated to the GGBFS. Furthermore, the EC of GGBFS based SCGC is noted by 1.17%, 2.34%, 3.50%, and 4.67% at 2.5MK2.5CBA, 5MK5CBA, 7.5MK7.7CBA, and 10MK10CBA which is higher than that of reference mix of GGBFS based SCGC at 28 days consistently. From the findings, it is noted that the EC of GGBFS based SCGC is reducing with addition of CBA alone and the addition of MK is increased the EC of SCGC alone and together with CBA.

RSM modelling and optimization

The development of response surface models and anova.

RSM is employed for the construction and development of response surface models, which are then evaluated applying ANOVA. For RSM modelling and optimization, the fresh, mechanical, and durability features of SCGC were considered with the inclusion of 0 to 20% MK and CBA alone or together as a GGBFS substitute. In addition, quadratic models were deemed more appropriate for the slump flow test, V-funnel flow test, and T50 flow test, CS, STS, FS, permeability, and sulfate attack test. Moreover, each of these responses is contained in Eqs. ( 2 )–( 9 ). Equations described in relationships of coded constituents may be utilized to predict the impact of changing parameter values. By default, the greatest levels of the constituents are represented as + 1 and the lowest values as − 1. Using the coefficients of the factors, the coded equations may be used to assess the variables' relative significance 98 , 99 , 100 . A and B are variables of input (MK and CBA). The ANOVA findings are shown in Table 4 .

In ANOVA, the significance level was established at 95%, meaning that any prototype component with a possibility lesser than 5% is measured statistically important. All of the produced approaches are statistically significant because their probabilities are below 0.05. The slump flow test model’s model terms A, B, AB, A 2 , and B 2 have statistical significance. A, B, AB, A 2 , and B 2 are also key model terms for the V-funnel flow test, T50 flow test, CS, STS, FS, permeability, and sulfate attack test. The coefficient of determination, often referred to as R 2 , is a crucial performance metric. It quantifies the model’s goodness of fit to the observed data and can range between 0 and 1, or be presented as a percentage from 0 to 100. A higher R 2 value indicates a better fit of the model to the empirical data, while a lower value suggests a weaker fit. Table 5 presents the R 2 value along with other evaluation factors for the models. R 2 values are observed by 99.53%, 99.85%, 99.25%, 97.65%, 93.20%, 97.85%, 99.83%, and 88.82% for slump flow test, V-funnel flow test, T50 flow test, CS, STS, FS, permeability, and sulfate attack test. Furthermore, "Adeq. Precision" computes the signal-to-noise ratio. A ratio greater than four is preferred. Precision values for the slump flow test, V-funnel flow test, T50 flow test, CS, STS, FS, permeability and sulfate attack test is 60.19, 112.03, 47.28, 22.78, 14.82, 25.69, 98.78, and 12.18, respectively, according to Table 5 . These results show that the models are capable of precisely anticipating responses.

Here, SFT, VFT, TFT, CS, STS, FS, WPD, and SAT are Slump Flow Test, V-Funnel Flow Test, T 50 Flow Test, Compressive Strength, Splitting Tensile Strength, Flexural Strength, Water Penetration Depth, and Sulphate Attack Test respectively.

The “Residual against Normal” diagram and the “Predicted against Actual” diagram, as shown in Figs.  10 , 11 , 12 , 13 , 14 , 15 , 16 and 17 for the eight parameters, are utilized as effective approach for more rapidly analyzing the condition and applicability of generated response models (SFT, VFT, TFT, CS, STS, FS, WPD, and SAT). All charts display the linearity of the data sets along the fit line to illustrate the accuracy of the created approaches. The arrangement of data facts on residual normal plots suggests that the error components have a normal distribution, which is desired. If 95% of the points lie between − 2 and + 2, which is true for all approaches 101 , 102 , residuals are often dispersed.

The effect of the relationships between the output responses and input factors is shown using 2D diagram and 3 D graphs. Figures  18 , 19 , 20 , 21 , 22 , 23 , 24 and 25 depict response surface plots for the SFT model, VFT model, TFT model, CS model, STS model, FS model, WPD model, and SAT model. In this case, both 2 D plots and 3 D graphs show how the MK and CBA interact. The graphs' color coding illustrates the size of the response as well as the various input feature values under consideration. Figure  18 a and b show the 2D and 3D plots for the slump flow test. The data showed that the control combination has a high intensity of slump at up to 15.33% MK and 4.71% CBA as GGBFS replacement material. Moreover, the slump flow of geopolymer GGBFS-based concrete diminishes when more MK and CBA alone and merge in matrix. The surface responses for permeability, and sulfate attack test are all similar. The V-funnel flow test of geopolymer GGBFS-based concrete rises when the proportions of MK and CBA in matrix. The T50 flow test produced similar surface reactions. Furthermore, Fig.  20 a and b show the 2D diagram and 3D graphs for CS, respectively. According to the graphs, a high concentration of CS has been stated as a GGBFS replacement material, up to 15.33% of MK and 4.71% of CBA. Furthermore, by including up to 15.33% MK and 4.71% CBA in the concrete, the strength value is substantially increased. This is owing to the void-filling and densification properties of MK and CBA as a pozzolanic material combination. The similar behaviour of response surface plots was observed for STS, and FS respectively.

Optimization

It is employed to analyse the ideal values of the independent variables that result in the highest possible output level. This is performed by creating quality objectives (input and output characteristics) with varied conditions and degrees of priority to achieve the intended purpose. The optimization is assessed via the desirability (0 ≤  dj  ≤ 1). The desirability rate is near to one which indicates the superior results 103 , 104 .

Table 6 illustrates the objectives and prerequisites for optimizing this scenario. However, the usage of MK and CBA as a substitute for GGBFS has been restricted to a range of 0 to 20% separate and combined, so that the system can select the appropriate amount required to fulfil the stated purpose. According to the optimization findings, the highest values for SFT, VFT, TFT, CS, STS, FS, WPD, and SAT could be obtained by 639.15 mm, 12.38 s, 5.23 s, 57.08 MPa, 5.50 MPa, 5.93 MPa, 13.31 mm, and 0.081%, respectively. Given the nature of the considerable response value variability, the optimization’s desirability is assessed to be 69.10%. Figures  26 illustrate 3D diagram for desirability.

Conclusions

This study examined the fresh, mechanical properties and durability of SCGC integrating the CBA and MK as a substitution for GGBFS alone and jointly. The following key points are drawn from this investigation:

The slump flow is decreased as the amount of GGBFS is replaced with MK and CBA alone and jointly rises in the production of SCGC grows. This drop-in slump flow is associated with the very fineness of CBA and MK particles and the specific surface area of GGBFS is lower as compared to MK and CBA.

The V-funnel flow time is boosted when the consumption of CBA and MK as a substitution for GGBFS alone and together rises in the production of SCGC that result in dropping the fluidity of SCGC.

The slump flow time is enhanced as the consumption of CBA and MK as a substitution for GGBFS alone and combined increases in the production of SCGC. This increase in the T 50 flow time is attributable to the increased paste volume achieved by using MK and CBA in place of GGBFS alone and together in the production of SCGC.

The peak CS is recorded by 59.86 MPa, 58.76 MPa, and 59.40 MPa at 10% of MK, 10% of CBA, and 5CBA5MK, and the lowest CS is noted by 52.50 MPa, 51.25 MPa and 52.20 MPa at 20% of MK, 20% of CBA and 10CBA10MK as a substitution for GGBFS in SCGC after 28 days, consistently. It has been perceived that the use of CBA and MK up to 15% as a substitution for GGBFS combined in SCGC is augmented the CS.

The maximum STS is recorded by 5.75 MPa, 5.63 MPa, and 5.68 MPa at 10% of MK, 10% of CBA, and 5CBA5MK, and the lowest strength is found by 5.18 MPa, 5.0 MPa, and 5.12 MPa at 20% of MK, 20% of CBA and 10CBA10MK as a substitution for GGBFS in SCGC after 28 days, consistently. Moreover, the use of CBA and MK up to 15% as a substitution for GGBFS combined in SCGC is increased the STS.

The maximum FS is recorded by 6.20 MPa, 6.0 MPa, and 6.12 MPa at 10% of MK, 10% of CBA, and 5CBA5MK, and the lowest FS is noted by 5.50 MPa, 5.35 MPa and 5.42 MPa at 20% of MK, 20% of CBA and 10CBA10MK as a substitution for GGBFS in the production of SCGC on 28 days, consistently. It has been perceived that the use of CBA and MK up to 15% as a substitution for GGBFS combined in the production of SCGC increased flexural strength.

The permeability plummeted as the consumption of MK and CBA alone and jointly as a substitution for GGBFS in the production of SCGC after 28 days.

The minimum change in length is recorded by 0.075 mm, 0.059 mm, and 0.062 mm at 15% of MK, 15% of CBA, and 7.5MK7.5CBA as a replacement for GGBFS while the maximum change in length is calculated by 0.096 mm, 0.10 mm and 0.11 mm at 20% of MK, 20% of CBA and 10CBA10MK as a substitution for GGBFS in SCGC at 180 days correspondingly.

The embodied carbon of GGBFS based SCGC is getting decrease when the concentration of CBA rises while the EC of GGBFS based SCGC is getting higher with addition of MK as substitution for GGBFS alone or combine with CBA in SCGC.

Response surface models predict GGBFS-based self-compacting geopolymer concrete’s fresh, mechanical, and durability characteristics using ANOVA. Models have R 2 values ranging from 88 to 99%. Using MK and CBA, desirability factor is 69.10%.
