Now a days, there is an imbalance in the ecosystem due to the over usage of some by-products. Here the major concern due to its harmful impact to environment. Several studies have been conducted to decrease severe effect on environment by using by products like copper slag as a replacing agent of fine aggregates. A complete review of studies has been discussed in this project for the chances of substitution of copper slag instead of fine aggregates in concrete. In this project we have discussed and investigated the impact of copper slag by substituting it with the fine aggregates at various levels of percentages. Here we evaluate the values of tensile strength, compressive strength .In this experiment, to determine the strength parameters, flexural strength and compressive strength, M30 grade concrete is used for curing of concrete in the duration of days of 3, 7 and 28.The results reveals that as there is an improvement in the Compressive Strength and Tensile Strength with the increase of content of copper, whereas the workability increases with improvement of copper slag percentage. Up to 35 % of replacement of copper slag with sand has a comparable strength with the control mix. But, additional replacement of copper slag leads to reduction in the strength.

Copper slag, Compressive Strength, Tensile Strength, Flexural strength.
