The environment problems are very common in India due to generation of industrial by products. Concrete is a composite construction material composed mainly of cement, fine aggregate, coarse aggregate and water. Fly ash is used as a supplementary cementitious material (SCM) in the production of portland cement concrete. A supplementary cementitious material, when used in conjunction with portland cement, contributes to the properties of the hardened concrete through hydraulic or pozzolanic activity. Copper slag is a by-product material produced from the process of manufacturing copper. To produce every ton of copper, approximately 2.2–3.0 tons copper slag is generated as a by-product material. In this project control mix is casted for M25 grade and the Fly Ash as cement replacement in range of 10%, 20% and 30% by weight of cement and the Copper Slag as fine aggregate replacement in 20%, 30%, 40% and 50% by weight of fine aggregate and the cubes are tested for compressive strength. The obtained results are compared with M25 grade conventional concrete. Durability properties like alkali resistance, salt resistance and sulphate resistance are determined.
