The Influences of Iron Ore Tailings as Fine Aggregate on

industry. As 75% of concrete is composed of aggregates it is imperative that we look to maximize the use of waste as aggregate input in concrete making. They have investigated to determines the effect of partial replacement of fine aggregates by steel slag on the mechanical properties of concrete. Mar 01, 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.
