Utilisation of copper slag for cement manufacture

2007-5-1  Copper slag admixed mortar and concrete showed a lesser amount of leaching than solution due to the complex formation with cement mortar. Hence, copper slag can be used (2.5%) in raw mix for OPC and (35%) in manufacture of PSC. The material does not have any adverse impact on the performance of OPC and PSC.
