Concrete is the most widely used building material. Successful examples of high rise buildings in the world are obvious evidences that the use of high strength concrete n now day?s reality in construction worldwide. Growing demand for construction materials necessitated the usage of alternative materials in the production of conventional concrete. Since there is a scarcity of fine aggregate throughout the country it is essential to find a replacement of fine aggregate. The objective of this work is to study the strength and durability properties of concrete. In this study M70 grade of concrete is used. An experimental investigation have conducted to study the properties of concrete containing copper slag as partial replacement of fine aggregate and mineral admixture as partial replacement of cement in the concrete mix design. Copper slag content has been 40%as a replacement of fine aggregate and silica fume 5%,10%,15% & 20% and GGBS 5%,10%,15% & 20% as a replacement of cement respectively .This research paper study on strength test& Durability test. The test results indicate that the strength properties of concrete were improved having copper slag as a partial replacement of fine aggregate ( 40%) and Silica fume &GGBS as partial replacement of cement (up to 15%). From the results, it was observed that the use of copper slag and mineral admixture in concrete has shown considerable increase in strength and reduction of cost when compared with normal concrete.
