The physical properties of copper slag are given in Table 2.As seen, the density of copper slag varies between 3.16 and 3.87 g/cm 3 based on the amount of iron content. The average specific gravity of copper slag is about 3.5 g/cm 3 that means copper slag is denser than ordinary natural aggregates. In general, water absorption of copper slag is very low.
