UTILIZATION OF IRON ORE TAILINGS AS REPLACEMENT TO FINE

In the present study Iron Ore Tailings (IOT) procured from Kudremukh Lakya Dam site (KIOCL Ltd.) are used as partial replacement to fine aggregates at levels of 10, 20,30,40,50 percent and the basic material properties, strength parameters are studied. It is found that as the IOT percentage increases in the mix workability is reduced.
