POTENTIAL USE OF COPPER SLAG IN MORTAR AND CONCRETE -A CRITICAL REVIEW

The construction activities are increasing day by day. Due to this the natural sand is increasing its scarcity and its price in all parts of the country. Therefore reducing the consumption of natural sand in construction is a major issue while considering the both environment and economic view. The sustainable development for construction involves the use of nonconventional, innovative materials and recycling of industrial by products in order to compensate the lack of natural resources. Copper slag is one of the industrial by-product obtained during manufacture of copper. This paper reviews the characteristics of copper slag and its effects on the engineering properties of cement, mortar and concrete.
