deep processing of water slag and iron

Liquid Slag

7.2.1 Ground granulated blast-furnace slag. The rapid quenching of molten liquid slag as a by-product from the reduction of iron ore to iron in a large volume of water produces granules like coarse sand aggregates. This process of production optimizes its cementitious properties. These granules are further dried and grounded to a fine powder form to obtain the GGBS.
