Abstract

This paper studied the possibility of using waste materials such as clay tiles and fly ash as substitute for coarse aggregate and cement respectively in concrete. Experimental studies were conducted on fresh and hardened concrete made with partial replacement of crushed granite coarse aggregate with broken tile and cement with fly ash. The experimental results showed that 20% and 30% tile aggregate concrete (TAC) attains 82% and 75% compressive strength of natural aggregate concrete (NAC). The replacement of cement with 25% of fly ash further reduces the strength in the initial age and at the later age, the strength gets improved and it attains 85% and 79% compressive strength of NAC for 20% and 30% tile aggregate concrete (TAC) respectively. The same scenario was found in tensile and flexural strength of tile aggregate admixed concrete. Hence these waste materials could be used in concrete within the limits of the results as obtained in the present experimental study
