Granulated Blast Furnace Slag Powder

Ground Granulated Blast Furnace Slag(GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. It is suitable for applications in marine environment, mass concreting and sulphate environment, water retaining structures, basement and other structures which require low heat of hydration. GGBFS is off-white in color and substantially lighter than Portland cement. The whitish color is also observed in concrete made with GGBS, especially at addition of 50% and above. The more pleasing appearance of GGBFS concrete can help soften the visual impact of large structure such as bridges, retaining walls, etc. Applications & Benefits for the Product: High-performance concrete additive, especially suitable for: Preparation of the harbor and marine concrete structures with high resistance to corrosion by chloride ion Preparation of corrosion resistant concrete, improving durability of concrete structure in soleplate salt and alkali regions Preparation of concrete which provides effective prevention measures for the potential active alkali-aggregate reactions in concrete Preparation of low heat concrete which, effectively reducing the risk of temperature cracks in early period of the mass concrete structure Preparation of pumping concrete to effectively reduce the slump loss in the construction in summer, hence improving the workability of concrete .
