The objective of this research study is to evaluate and study the possibility of using ceramic tiles wastes as a substitute on the coarse aggregate of normal strength concrete, In order to determine the viability of this study, the researchers designed mixtures with 25%, 50%, 75% and 100% substitution of ceramic tiles wastes. The resulting cylindrical specimens would then be compared to control specimens via compressive strength tests. Through this, the researchers would conclude which percent substitution yields the highest compressive strength. We limited the source of tiles to one place, an outlet that sells tiles situated in Cavite, in order to achieve uniformity. The cement, water, gravel and fine aggregates were obtained from Filmixco, a concrete mixing company in San Fernando, Pampanga. The compressive strength tests show that the samples with 25% and 50% substitution, along with the control specimen, exceeded the target strength of 15 MPa. The tests show that the samples of the traditional mix had the highest average compressive strength, followed by the 25%, 50%, 75% and 100% group. However, when statistical analysis was performed on the control specimens and the samples with 25% of files as coarse aggregates, it was discovered that at a 90% confidence level, it can be concluded that the data are too close that it is not safe to say that control specimens have a higher compressive strength that the tiles of the 25% group.
