  • Characterization of Iron Ore Tailings as Fine Aggregate

    01/03/2020 · Abstract: Iron ore tailings (IOTs) are common industrial solid waste products which are generated in enormous quantities during the production process of iron ore. By visual observation, this material shows some similarity with natural sand (NS); it was therefore desired to characterize the IOTs to further ascertain their use in concrete.
