Effects of iron ore tailings on the compressive strength ...

10/11/2020  Iron ore tailings (IOT) are discharged as waste after the beneficiation process to concentrate iron ore, which has triggered a series of environmental problems. The influence of IOT as a replacement for manufactured sand (MS) (0%, 20%, 40%, 60%, 80%, and 100% by weight) on the compressive strength and permeability of UHPC mortars was investigated by multiple methods
