Utilization of Iron Ore Waste and Tailings in Concrete Pavements
This thesis investigates utilizing iron ore mine waste and tailings as aggregates in concrete pavements. Concrete mixes were developed with partial replacement of coarse aggregates with iron ore waste rock (WR) and partial replacement of fine aggregates with iron ore tailings (IOT) at different percentages. Concrete properties such as compressive strength, flexural strength, …
