Ceramic wastes are found to be suitable for usage as substitution for fine and coarse aggregates in concrete production. This study is an investigation into the utilization of waste tiles as partial replacement for fine and coarse aggregates in concrete. The control mix and other mixes containing cement, water, granite and partial replacement for sand with crushed tiles (in 5%, 10%, 15% and 20% proportions) were cast, cubed, cured and crushed. Also, another mix containing cement, water, sand and partial replacement of granite with crushed tiles (in 25%, 50% and 75% proportions) were cast, cubed, cured and crushed. The specimens were tested for their respective compressive strengths using the Universal Testing Machine (UTM) on the 7
th , 14th , 21st and 28th days of curing. At 28 days, the compressive strength value of 5% of fine-waste tiles replacement was 20.12 N/mm² while that of 10%, 15% and 20% were 14.24 N/mm², 11.04 N/mm2 and 10.12 N/mm² respectively. Moreover, at 28 days, the compressive strength of 25% of coarsewaste tiles replacement shows an increase to 22.45 N/mm² while that of 50% and 75% were 18.4 N/mm2 and 12.2 N/mm² respectively. Thus it can be concluded that fine aggregates can be substituted at 5% waste tiles while coarse aggregates can be substituted at 25% waste tiles. [ABSTRACT FROM AUTHOR]- Published
