Studies on Mechanical Properties of SCC with Construction and Demolition Waste as Coarse and Fine Aggregates

Abstract

India being a fast growing economy has caused a boost in the construction industry. Increase in construction activities has resulted in accumulation of construction and demolition waste. These waste materials like mortar, concrete, tiles, glass, wood etc being non-biodegradable lead to pollution and also waste of land resource when used as dumping yards. As a solution to this problem these waste generated must be reduced, reused and recycled. For this purpose the coarse and fine aggregate content in SCC is attempted to be replaced by crushed construction and demolition waste. The objective of the research project is to study the mechanical properties of SCC when the fine aggregates are replaced by C&D waste in different percentages and hence to find the optimum replacement. Two cases will be investigated with five different types of C&D waste ie concrete waste, mortar waste, crushed tiles and manufactured sand as fine aggregate and recycled concrete aggregate as coarse aggregate where in one only the fine aggregate will be replaced where as in the second both coarse and fine aggregate will be replaced simultaneously .
