Product Description

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten ironslag(a by-product of iron and steel-making) from ablast furnacein water or steam, to produce aglassy, 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 colour and substantially lighter than Portland cement. The whitish colour 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.
