Utilization of copper slag in cement and concrete

Moura et al. (1999) investigated the compressive and flexural strength of concrete containing copper slag as 10% of the cement by mass. The results indicated Trixier et al. found that replacing OPC by copper slag in blended cement increases the total porosity but decreases the capillary porosity (pores < 500 nm). This means that the microstructure is densified which contributes to increasing the compressive strength .
