Also Table 2 shows that there is general slight increase in the density of high performance concrete with the increase of copper slag quantity. The density of concrete was increased by almost 5%. This is mainly due to the higher specific gravity of copper slag which was 3.4 compared with sand which has a specific gravity of 2.77.
