The construction industry is continually seeking sustainable alternatives to traditional building materials to mitigate environmental impact while maintaining structural integrity. In this study, we investigate the feasibility of using fly ash as a partial replacement for cement in concrete blocks. Fly ash, a byproduct of coal combustion, possesses pozzolanic properties that can enhance the strength and durability of concrete. Our research focuses on a comparative analysis of cement blocks with varying proportions of fly ash replacements. We evaluate the compressive strength, density, water absorption, and durability characteristics of these blocks compared to conventional cement blocks. Through a series of laboratory experiments and statistical analysis, we aim to determine the optimal percentage of fly ash replacement that balances environmental benefits with structural performance.

Additionally, we explore the economic implications of incorporating fly ash in cement blocks, considering factors such as material cost, production efficiency, and long-term maintenance requirements. By providing insights into the mechanical, physical, and economic aspects of fly ash incorporation, our study contributes to the body of knowledge on sustainable construction practices and offers practical recommendations for industry stakeholders.
