Ground granulated blast-furnace slag (GGBFS) Our slag cement CEMSlag TM is a hydraulic cement material created when granulated blast-furnace slag from the steel manufacturing process is ground to a fineness suited for concrete production. Environmentally friendly and reduced greenhouse gas emissions.
Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse gas emissions by more than 40% and lowers the embodied energy of concrete by more than 30%. Another factor is slag cement's nearly white color.
The use of GGBFS as a partial Portland cement replacement takes advantage of the energy invested in the slag-making process and its corresponding benefits with respect to the enhanced cementitious properties of the slag. Grinding slag for cement replacement requires only about 25% of the energy needed to manufacture normal …
