alternative material to natural sand. Some alternatives materials have already been used as a replacement of natural sand such as fly-ash, quarry dust or limestone and siliceous stone powder, filtered sand, copper slag are used in concrete and mortar mixtures as a partial or full replacement of natural sand (Chandana Sukesh et al 2013)[9].

There was a decrease in the surface water absorption as copper slag quantity increased up to 40% replacement. Beyond that level of replacement, the absorption rate increases rapidly. 5. It is recommended that 40 wt% of copper slag can be used as replacement of sand in order to obtain HPC with good properties. 6.
