In this thesis, the researchers aim to study the effect of partial substitution of ceramic tiles wastes as coarse aggregates on the compressive strength of concrete. This idea was developed to give solution to the continuous increase of ceramic tile waste in the Philippines. The experimentation was done by using two types of ceramic tiles: glazed and unglazed. Three water-cement ratio was also utilized in the study: 0.4, 0.5 and 0.6, with 10%, 20%, 30%, 40%, & 50% partial substitution of ceramic tile waste and three different kinds of concrete mixes: pure glazed, pure unglazed and mixed tiles. The concrete mix was designed by pre-testing the materials. To obtain the compressive strength of the cylindrical concrete samples, the universal testing machine was used. The results showed that the pure glazed and mixed type samples with 0.4 water cement ratio with 10% and 20% partial substitution as well as pure glazed samples with 0.5 water-cement ratio with 10% partial substitution gave higher compressive strength than the conventional. Higher compressive strength was observed at 0.4 water-cement ratio compared to 0.6 water-cement ratio and the 20% substitution of glazeds ceramic tiles gave the highest compressive strength.
