In this work, an extensive study using copper slag has been carried out to investigate strength, workability and durability. Copper slag is an industrial by-product material produced from the process of manufacturing copper. For, 2.2 tonnes of copper slag is generated at every ton of copper production In the world of copper industry, it has approximately 26.6 million tons of copper slag are generated. Copper slag as a substitute for conventional fine aggregate with partial or full replacement using M25 grade concrete The main objective is to encourage the use of these seemingly waste products as a construction material. In this paper , the effect of using copper slag as a fine aggregate on properties of cement mortars and concrete various mortars & concrete mixtures were prepared with different proportions of copper slag ranging from (0CS+100S)%, (10CS+90S)%, (20CS+80S)%,(30CS+70S)%, (40CS+60S)%, (50CS+50S)%, (60CS+40S)%, (70CS+30S)%, (80CS+20S)%, (90CS+10S)%, (100+0S)%. Form the above test result we concluded that the 50% CS+50% S gives optimum proportional of CS that can be used as a replacement substitute material for fine aggregate in concrete. The design M25 grade concrete for 50% replacement of CS show the HPC characteristics. The design M25 grade concrete for 30% replacement of CS show the HPC characteristics. We can fully replace (100%CS) by fine aggregate in concrete, because of above all test result more than control mix. We can used any proportion of CS replacement as pre our requirement for creating concrete, because we concluded that the all result of replacement of CS is more than control mix.
