Investigation on Replacement of Fine and Coarse Aggregate by Waste Materials in Concrete

Abstract

This paper investigates the properties of waste materials in concrete of strength M25 using cuddapah waste
aggregate as partial replacement of conventional coarse aggregate and copper slag as partial replacement of fine aggregate
by focusing on its ability for compressive strength. For this purpose, seven mixes were prepared with different replacement
ratio (0,10,20,30,40,50 and 100) by weight of cuddapah waste aggregate with coarse aggregate, and five mixes were
prepared with different replacement ratio (20, 40, 60, 80 and 100) by weight of copper slag with fine aggregate. Tests were
conducted on fresh and hardened concrete after a curing period of 7 and 28 days. The evaluation of concrete quality had
done by Destructive and Non-Destructive tests. The results of experimental had been conducted that the 40% replacement of
cuddapah waste aggregate and copper slag instead both conventional aggregate is achieved the target strength as well as
combined waste aggregate concrete. The use of cuddapah waste aggregate or copper slag or both in concrete provide
potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable
amount of both are produced.
