This research examined tile waste as a partial replacement for coarse aggregate in concrete production. The aim was to evaluate the effects of adding tile waste on concrete. Tile wastes were added to the concrete mix in varying proportions of 0%, 10%, 20%, and 30%. Cement, fine aggregate, coarse aggregate, and water are primary materials. A series of tests were conducted to assess the performance of the concrete, including a Sieve analysis to determine the grading of fine aggregates, a slump test to measure workability, a compressive strength test to evaluate load-bearing capacity, and a water absorption test to assess durability. The results were compared to a control mix of 0% tile waste, demonstrating how different percentages of tile waste affected the concrete's workability, strength, and durability. The findings showed that tile waste has the potential to be a viable alternative to conventional aggregates, contributing to sustainable construction practices by reducing waste and conserving natural resources.
