Abstract: This project investigates the potential of using sintered fly ash, a waste by-product of thermal power plants, as a partial replacement for coarse aggregate in m25 grade concrete. The study aims to address sustainability in construction by reducing natural aggregate consumption and utilizing industrial waste effectively. Concrete mixes were prepared with sintered fly ash replacing coarse aggregate at varying levels (5%, 10%, 15%, and 20%) to analysis its influence on mechanical and durability properties, well as durability characteristics such as water absorption and permeability. The findings will contribute to understanding the optimal sfa content for achieving desired concrete performance while promoting the utilization of industrial byproducts. The study involves designing concrete mixes with varying percentages of sfa replacing coarse aggregate. Mechanical tests, including compressive and tensile strength tests, will be conducted on these mixes at different ages (e.g., 7, 14, and 28 days) to assess strength development. Durability tests, such as water absorption and permeability tests, will be performed to evaluate the concrete's resistance to moisture and other environmental factors. The results will be analyzed to determine the optimal sfa content that maximizes strength and durability while minimizing any negative impacts. This research is crucial for promoting sustainable construction practices by effectively utilizing sfa in concrete production.
