GGBFS

Grounded Granulated Blast Furnace Slag (GGBFS) is a byproduct from the blast-furnaces used to make iron. The major use of GGBFS is in ready-mixed concrete. In the production of ready-mixed concrete, GGBFS replaces a substantial portion of the normal Portland cement content, generally about 50%, but sometimes up to 70% or more. The higher the proportion, the better is the durability. GGBFS is also used in other concrete production. Different mixing ratio of products can produce concrete with different characteristics.
