Water slag is formed by rapidly cooling the molten blast furnace slag in water. There are mainly two ways: water quenching in slag pool and water quenching in front of furnace. Water slag is used as building materials for cement and concrete production. Due to its potential hydraulic cementitious properties, water slag can be used as high-quality cement raw materials under the action of cement clinker, lime, gypsum and other activators, and can be made into slag Portland cement, gypsum slag cement, lime slag cement, slag brick, slag concrete, etc, It can also be used as a raw material for producing environmental friendly cement brick.
According to the content of iron, the hardness and grindability of water slag are quite different.
