Experimental study of Compressive Strength of Concrete by Partial Replacement of Cement with Egg Shell Powder and Fine Aggregate with Copper Slag

Abstract

The Egg Shell Powder (ESP) is a waste generated from houses and hotels, impacting the environment. This study aims to reuse ESP and Copper Slag in concrete, partially replacing cement and fine aggregate to minimize their use, reduce pollution and ease the burden on natural resources. M20 and M25 grade concrete mixes were prepared with 5% & 7.5% ESP replacement for cement and 40% and 60% Copper Slag replacement for fine aggregate. It is concluded that there was an increase in the compressive strength of concrete with 5% ESP and 40% Copper slag, 5% ESP and 60% Copper slag, and 7.5% ESP and 40% Copper slag when compared to conventional concrete. However, the compressive strength decreased with 7.5% ESP and 60% Copper slag.
