Partial Replacement of Sand and Cement by Iron Ore Slime for Concrete Building Material

Abstract

Iron ore slime is a waste material generated after beneficiation of iron ores. It causes air, water and land pollution. From resource conservation point of view, the recovery of iron values is important and their use in different application. Researchers are also trying to find out value-added alternative application of iron ore slime rejects. In this paper, iron ore slime was used in concrete building material and evaluated the partial replacement of sand and cement in concrete. It was observed that the compressive strength of the concrete block was either equal or better with 15% partial replacement of cement and 20% partial replacement of sand with iron ore slime, respectively.
