Partial replacement of coarse aggregate by using ceramic tile aggregate in concrete

Abstract

There is a growing interest in using waste materials such as ceramics as alternative aggregate materials for construction. The current study focuses on the mechanical properties of waste ceramic floor tiles aggregate concrete. Ceramic wastes sourced from construction and demolition wastes were separated from other debris and crushed using a quarry metal hammer. Ceramic tiles were sieved into coarse aggregates in line with standards. Other materials used were gravel, river sand, cement and portable water. Workability of the fresh concrete was checked through slump test, and concrete cubes of 150 mm dimensions and cylinders of 100mm were cast in the laboratory. After 24 hr of casting, the concrete samples were demoulded and were cured by immersion in water tank at temperature of 22 °C. The compressive and split-tensile strengths of the hardened concrete samples were determined after curing them for 7 and 28 days. Results showed that both the compressive strength and split tensile strength increased appreciably with the curing age than the conventional concrete.
