Ground Granulated Blast Furnace Slag

GGBFS is a by-product from iron production in blast furnaces. The blast furnace naturally separates from the iron, then collected and cooled with large amount of cold water. This quenching process leads to transformation of liquid into small sized particles having amorphous particles' structure.

The major use of GGBS applies to ready-mixed concrete. During the production of ready-mixed concrete, GGBS replaces about 50% of normal Portland cement content, generally about 50%, but sometimes up to 70%. The higher the proportion, the better is the durability. The disadvantage of the higher replacement level is that early-age strength development is somewhat slower. GGBS is also used in other forms of concrete, including site-batched and precast.
