Granulated Blast Furnace Slag or GBFS is the residue of combustion in the furnace of the steel refining process. It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy substance.
GGBFS or Ground Granulated Blast Furnace Slag is formed when GBFS is further processed or grounded using conventional cement clinker grinding technology.
