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.
Uses and Benefits of GBFS/GGBFS
GGBFS or GBFS is the most used raw material in cement industry to make slag cement.
Raw material for the manufacture of glass
GBFS can be used as a substitute for sand in building materials
GGBFS can be used as a replacement for Portland cement
Reduced chloride permeability
Improved resistance to sulphate attack
Reduced heat of hydration in mass concrete
Improved compressive and flexural strength
Reduced alkali-silica reaction
Long slump retention
Greater durability and thermal resistance
