Experimental Investigation Of Effective Replacement Of Cement and Fine Aggregate By Copper Slag

Abstract

Copper slag is considered as one of the waste materials which can have a promising future in construction industry as partial or full substitute of either cement or aggregates. For each ton of copper production, about 2.2 tonnes of copper slag is generated. This slag is currently used for many purposes like land filling, construction of abrasive tools, roofing granules, cutting tools and rail road ballast material, which are not very high value added application. These applications utilize only about 15% to 20% of copper slag generated and remaining material is dumped as a waste. In order to reduce the accumulation of copper slag and also to provide an alternative material for sand and cement an approach has been done to investigate the use of copper slag in concrete for the partial replacement of sand and cement.
