Thesis Abstract

Abstract
Concrete is one of the most widely used construction materials worldwide, contributing significantly to the built environment. However, the production of concrete is associated with significant environmental impacts, including high energy consumption and carbon emissions. In response to growing concerns about sustainability in the construction industry, there is a need to optimize concrete mix designs to improve performance while reducing environmental impacts. This thesis focuses on the optimization of concrete mix designs for sustainable construction practices, aiming to achieve a balance between environmental, economic, and social considerations. The introduction chapter provides a background to the study, highlighting the importance of sustainable construction practices and the role of concrete in the built environment. The problem statement identifies the need for optimizing concrete mix designs to address environmental challenges while meeting performance requirements. The objectives of the study are to develop optimized concrete mix designs that minimize environmental impacts, reduce costs, and improve long-term performance. The limitations and scope of the study are outlined, along with the significance of the research in advancing sustainable construction practices. The structure of the thesis is also presented, outlining the chapters and their contents. The literature review chapter examines existing research on concrete mix design optimization, sustainable construction practices, and environmental impacts of concrete production. Key factors influencing concrete performance and sustainability are identified, providing a foundation for the research methodology. The research methodology chapter outlines the experimental approach, including materials selection, mix design optimization methods, and testing procedures. Factors such as cement replacement materials, aggregate selection, and water-cement ratio are considered in the mix design optimization process. The findings chapter presents the results of the experimental testing, including the performance of optimized concrete mix designs in terms of strength, durability, and sustainability indicators. The discussion of findings chapter provides an in-depth analysis of the results, comparing the performance of optimized mix designs with conventional concrete mixes. Factors influencing the environmental and economic sustainability of the optimized mixes are discussed, highlighting the potential benefits of adopting sustainable concrete mix designs in construction projects. In the conclusion and summary chapter, the key findings of the research are summarized, and the implications for sustainable construction practices are discussed. Recommendations for future research and practical applications of the optimized concrete mix designs are presented, emphasizing the importance of integrating sustainability principles into concrete production and construction practices. Overall, this thesis contributes to the advancement of sustainable construction practices by providing a framework for optimizing concrete mix designs to achieve environmental, economic, and social sustainability goals.
