There is a growing interest in using waste materials such as ceramics as alternative aggregate materials for construction. While other wastes of ceramic products, such as sanitary ware and electrical insulation, have been extensively investigated, there are not many findings available on ceramic tile wastes. Therefore, the current study focuses on the mechanical characterization of ceramic wall residues and aggregate concrete floor. Ceramic wastes from construction and demolition wastes were separated from other debris and crushed using a quarry hammer. Ceramic tiles were sieved into fine and coarse aggregates in line with standards. Other materials used were gravel, river sand, cement and drinking water. The viability of the fresh concrete was verified by a settlement test, and 150 mm concrete cubes of 100 mm x 200 mm dimensions and cylinders were molded in the laboratory. After 24 h of casting, the concrete samples were demolded and cured by immersion in a water tank at a temperature of 22 ° C. The compressive strengths and tensile strength of the hardened concrete samples were determined after to cure them for 3, 7, 14 and 28 days. The results showed that both the compressive strength and the split tensile strength increased appreciably with the curing age than conventional concrete.
