The present paper explains about the utilization of high volume copper slag in concrete. The study leads towards cleaner production, by utilizing industrial by-product i.e. copper slag as a replacement to natural river sand as fine aggregate. In this literature several studies have highlighted the various aspects of copper slag in developing it as a valuable resource. However there are very limited studies available about the performance of copper slag in high strength concrete. The main aim of the present research is to make the structural high strength concrete by using copper slag. This research work was carried out in two phases to find the strength of concrete. In the first phase the fine aggregate was replaced with copper slag in various percentages of 0%, 20%, 40%, 60%, 80% and 100%. In the second phase, cement was replaced with Nano silica (i.e. 1%, 2%, and 3%) to get maximum strength as well as impermeable concrete. The performance of concrete mixtures containing copper slag and Nano silica in terms of compressive strength, split tensile strength, flexural strength and water absorption were studied. From all these studies it could be determined that high volume copper slag with 100% replacement as fine aggregate in high strength structural concrete is technically viable.
