Partial replacement of coarse aggregates with terracotta aggregates in concrete

Abstract

In this industrialized world, the amount of Construction and Demolition Waste generated worldwide seems to be huge. Employing these wastes as substitute for coarse aggregates in concrete is an important consideration both economic and environmental wise. A study has been made on properties of terracotta aggregate which is to be used as coarse aggregate. The percentage of terracotta aggregate that partially replaced coarse aggregate by weight was 0%,10%,20%,30%,40% and 50%. Concrete cubes were casted and tested in the laboratory. Properties of aggregate and comparison of terracotta aggregate concrete against coarse aggregate concrete was performed according to requirements as such for its workability and compressive strength test. The results show that greater than 30% replacements of coarse aggregate are not suggested as specific gravity, water absorption and compressive strength are not fit for desirable concrete properties.
