3.3. Physical properties. The typical copper slag is generally black or dark brown in colour and its density is in the range of 3.2 – 4.5 g/cm 3, mainly depending on the content of Fe (Sarfo et al., 2017b).The average true density of copper slag is approximately 3.8 g/cm 3, which is denser than the ordinary natural aggregates (Shi et al., 2008). ...
