What is the difference between opc cement and portland slag cement?

Portland Slag Cement is a variation of Portland Cement. Slag materials namely fly ash, volcanic ash, are added to the Ordinary Portland Cement (OPC) so that it becomes Portland Slag Cement. Both are eco-friendly materials but Slag Cement uses natural and industrial waste thus reducing the environmental pollution. Slag Cement is cheaper than OPC cement. Slag Cement has low initial setting strength compared to OPC cement but hardens over a period of time with proper curing.
