CHARACTERIZATION OF MATERIALS BY PARTIALLY REPLACING CEMENT BY COPPER ORE TAILING AND SAND BY IRON ORE TAILING

Abstract

The construction industry has been improvising through the advances in innovation and procedure. Concrete, which is the essential part in development industry, is being utilized more than manmade materials and it expands more crude materials. Cement, fine aggregate and coarse aggregate are vital ingredients of concrete .An earnest attempt is made through this project to fulfill all the pre and post factor of M20 concrete by partial replacement of cement by copper ore tailing of 5%, 10%, 15%, 20%, 25% and sand by iron ore tailing of 10%, 20%, 30%, 40%, 50%. The effect of copper ore tailing and iron ore tailing for the partial replacement of cement and sand on strength and durability characteristics were analyzed and compared with normal concrete. The test results shows that 15% copper ore tailing and 30% iron ore tailing shows the good and optimized results. Its use will lead to a reduction in cement and sand quantity required for construction purposes and hence sustainability in the construction industry.
