Strength and durability of concrete by partial replacement of sand by Copper Slag and cement by Egg Shell Powder: A Review

Abstract

From some decades the production and use of concrete has been increased. The manufacturing process of concrete as well as the three main ingredients emits lots of harmful gas like CO2 which directly harm the environment. In this study, relevant study done on the fine aggregate and cement replacement with egg shell powder & copper slag were discussed. Also effect of cement and fine aggregate replacement on compressive strength and durability of concrete had been discussed. From study it has been observed that the egg shell powder and the copper slag can't affect much the durability and strength parameters up to 6% and 40% replacement of cement and fine aggregate. Also observed that copper slag and egg shell powder reduced impact of concrete on environment but still need to improve the manufacturing process of copper slag.
