Utilization of iron ore tailings as fine aggregate in ...
2014-1-15 Iron ore tailings have the potential to be used as fine aggregate because they are relatively inert and the particle size of the tailings is significantly larger than that of cement. This paper investigated the use of iron ore tailings to replace natural sand as fine aggregate and studied the impact that various replacement levels had on the mechanical properties of UHPC.
