Ground granulated blast-furnace slag - Wikipedia
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.Ground-granulated blast furnace slag is highly cementitious and high in calcium silicate hydrates (CSH) which is a strength enhancing ...

GGBS - Ground Granulated Blast Furnace Slag for Concrete!
Ground granulated blast furnace slag (GGBS) is a non-metallic product obtained as a byproduct from the blast furnaces used to make iron. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. The size of its particles is less than 45 microns and specific surface area is about 400 to 600 m 2 /kg.
