Waste generation in unpredictable amounts is a part of almost every metal and non-metal casting industry. These wastes can be converted to useful material if processed for ultimate recovery of valuables provided it is economical. Dumping of these wastes may lead to environmental problems. Therefore, the reuse of the waste materials in various fields is seen for quite some time. Copper slag is a waste product generated during the smelting process for the production of copper. It has been estimated that for every tonne of copper produced, about 1.8-2.2 tonnes of copper slag is generated as a waste. Due to increase in production capacity of copper, copper slag getting accumulated require additional dumping space and causing wastage of good cultivable land. The present paper discusses the laboratory test results of direct shear tests conducted on copper slag mixed with cement. The copper slag mixed with cement in various percentages were kept for curing and then tested after 7, 14, 28 days. Effective results are observed for the shear parameters like cohesion and angle of internal friction of copper slag on addition of 6% of cement and 6% of lime. There is an increase in cohesion and decrease in angle of internal friction with the addition of cement when compared to that of lime.
