Assessing Concrete Strength with Partial Coarse Aggregate Replacement by Ceramic Tile Waste

The use of waste materials in concrete production has gained significant attention in recent years due to sustainability concerns and the need for resource conservation. This research examines the effectiveness of ceramic tile waste as a partial replacement for coarse aggregate in M30-grade concrete. The objective is to evaluate the impact of different replacement percentages (25%, 50%, and 75%) on the compressive strength and split tensile strength of the concrete. Experimental investigations were conducted to compare the performance of concrete mixes containing ceramic tile waste with a reference concrete mix that contained no waste material. Compressive strength and split tensile strength tests were performed on concrete specimens at varying curing durations (7, 14, 21, and 28 days). The test results were analyzed and compared to assess the effect of ceramic tile waste replacement on the concrete's mechanical properties. The experimental results indicate that replacing up to 25% of the coarse aggregate with ceramic tile waste is feasible without significantly compromising the overall strength of M30-grade concrete. However, higher replacement percentages (50% and 75%) may necessitate additional measures, such as modifying the mix design or incorporating supplementary materials, to mitigate the strength reduction. Additionally, using ceramic tile waste offers environmental benefits by reducing the demand for natural resources and diverting waste from landfills.
