Experimental Study of Copper Slag on Mechanical Properties of Concrete

摘要

This paper is about the experimental study of effect of copper slag as partial replacement of fine aggregate on mechanical properties of concrete. In this study, M30 grade concrete was considered to study the strength of concrete developed for the curing period of 7 and 28 days. Accordingly, tests were conducted for various proportions of sand replacement with copper slag of 0%, 25%, 50% and 75% in concrete. Concrete samples were produced, tested and compared in terms of compressive and split tensile strengths. From the results, it is concluded that the maximum strength is attained at 50% replacement of copper slag as fine aggregate.
