Utilisation of copper slag for applications such as Portland cement replacement in concrete, and/or as a cement raw material has the dual benefit of eliminating the costs of disposal, and lowering the cost of the concrete (Mobasher et al., 1996). Some of the properties of copper slag are favourable for its use as an aggregate …

The addition of CaCO 3 to the cement and copper-tailed slag-based cement materials enhance inter-particle bonding, structural compactness, and reduces the number of pores within the test block, thereby reducing the amount of pore water that can be accommodated. Consequently, the damage caused by the expansion of ice crystals …
