Iron Ore Tailings (IOT) are the waste slag resulted from iron ore mines. Large amount of Iron Ore Tailings (IOT) have been generating every year posing serious environmental problems, large production of cement everyday resulting the emission of CO 2 and increase in the consumption of river sand for construction activities making the river beds over-exploited.

The results indicate that the incorporation of copper mining tailing and copper slag with lower replacement levels (up to 10% by weight) can have comparable mechanical performance with the reference mixtures. XRD and TGA results demonstrate the filler effect of both copper mine wastes in terms of bound water and calcium hydroxide precipitation.
