Concrete has been the most preferred construction material for over five decades.The problem of how to meet the increasing demand and cost of concrete in sustainable manner is a challenge in the field of civil engineering and environmental studies. Alternative materials generally used are mainly the industrial wastes which are facing the problems of safe disposal and cause environment hazards. Copper Slag and Fly Ash are such industrial wastes in huge quantity facing the safe disposal.In view of the above, An Experimental study carried on concrete by partial replacement of fine aggregate with copper slag and cement with fly ash in concrete production.This experimental study mainly consists of two parts. In first part optimum percentage of Copper Slag and Fly Ash were determined individually by testing the compressive strength of cement mortar cubes with various percentage replacement of fine aggregate with Copper slag and various percentage replacement of cement with Fly Ash. In second part optimum percentage of Copper Slag and Fly Ash together added to the concrete and various strength parameters were determined for M20 and M25 grade concretes. The obtained results were compared with those of control concrete made with ordinary Portland cement and fine aggregate. The results indicate that there is gain in strength and better resistant for durability tests.
