Abstract
Sustainability and resource efficiency are becoming increasing important issues within today’s construction industry. Granulated copper slag (or) copper slag which is a by-product of metallurgical operations in Sterlite industries (India) Ltd. For every tone of metal production, about 2.2 ton of waste slag is generated. Dumping or disposal of such large quantities of slag cause environmental and space problems.This study reports the potential use of granulated copper slag from Sterlite Industries as a replacement for sand in concrete mixes. In this project work, the concrete grade M25 was selected and IS method was used for mix design. The properties of the material for cement, fine aggregate, coarse aggregate and copper slag were studied for mix design. The effect of replacing fine aggregate by copper slag on the compressive strength and split tensile strength are attempted in this work.The percentage replacement of sand by granulated copper slag was 0%, 15%, 30%, 40% and 45%. The compressive strength was observed to increase by about 35-40% and split flexure strength by 30-40% and split tensile strength by 30-35%. The experimental investigation showed that percentage replacement of sand by copper slag should be up to 40%.
