When compared to reference concrete, the TS shown by the concrete with iron ore tailings aggregate improved by 4.8% with age . However, because of the greater fines content, the concrete with iron ore tailings aggregate would need more water to mix, which weakens the link between the aggregate and cement paste, and lowers the TS .
