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

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.
