Iron ore in concrete. iron ore tailing IOT as fine aggregate would turn this waste material into valuable resources reduction in the strain on the supply of natural sand and economy in concrete production World production averages one billion metric tons of raw ore annually
For the normal concrete, conventional materials such as sand, cement and granite aggregates were used. For the tailings concrete being studied, iron ore tailings were used together with the cement to make the new concrete. The iron ore tailings were obtained from Mount Gibson Iron Extension Hill Operations in Perenjori of Western Australia (WA).
