Utilization of industrial waste and secondary materials is very much encouraged in construction industry and gaining importance. This concept supports in minimizing the environmental hazard and health problems. Copper slag is also one of the material considered as an industrial waste which can be used in construction Industry contribute to the reduction in consumption of natural resources. Many researchers have investigated the use of copper slag in the production of cement, cement mortar and cement concrete as raw material for clinker and as a partial replacement for cement, coarse aggregate and fine aggregate. The use of copper slag in cement and concrete extends potential environmental as well as economic benefits for all related industries, particularly in areas where considerable amount of copper slag is produced. In the present study experimental investigation has been carried out to identify the influence of Copper Slag (CS) on the properties of concrete. Concrete cubes are made with 20%, 30%, 35%, 40%, 45%, 50% and 55% replacement of fine aggregate with copper slag. They were casted and the compressive strength of concrete cubes after 7 and 28 days of curing is determined along with evaluation of workability of concrete. The results have shown that all mixes with different copper slag yield increase in compressive strength than that of the control mix. The workability increased significantly as copper slag percentage increased compared with the control mixture. A substitution of up to 40–55% copper slag as a replacement of fine aggregate yielded good compressive strength compared with controlled concrete mix. The obtained results were compared with those of control concrete made with ordinary Portland cement and river sand. Therefore, it is recommended that up to 40–55% (by weight of sand) of copper slag can be used as a replacement for fine aggregates in order to obtain concrete with enhanced strength apart from minimizing environmental hazard. © 2021, The Society for Experimental Mechanics, Inc.
