Ground-granulated blast-furnace slag (GGBFS) is a by-product of iron and steel-making obtained by quenching molten iron slag from a blast furnace in water or steam. Used to increase the strength of concrete and used to improve workability of fresh concrete and reduce water demand, shrinkage and permeability of the finished product.

After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement clinker to make Portland cement. Typically, granulated slag is ground to an air-permeability (blaine) fineness exceeding that of Portland cement to obtain increased hydraulic activity at early ages.
