Range of Blast Furnace Slag Products
Granulated Blast Furnace Slag (GBFS)
GBFS is a by-product of steel production in a blast furnace. In its molten state, it is rapidly quenched with water in a granulator, causing it to cool and solidify into glassy, non-metallic granules composed of calcium silicates and aluminosilicates. These granules are then dried to produce GBFS, a valuable material for cement and concrete production.
Ground Granulated Blast Furnace Slag (GGBFS)
GBFS is further processed through advanced grinding techniques using vertical roller mills or ball mills, ensuring controlled fineness, particle distribution, and shape. This precision grinding results in GGBFS, a high-performance, off-white material that enhances strength, durability, and sustainability in concrete applications. Its consistent quality and reactivity make it an ideal substitute for conventional cementitious materials, improving overall construction efficiency.
