Water slag refers to ironmaking blast furnace slag?

Water slag refers to ironmaking blast furnace slag. It is in a high-temperature molten state and is rapidly cooled with water to form a granulated foam shape, milky white, light, crisp, porous, and easy to grind into fine powder. It is a soft material for foamed silicate building products, slag sound-absorbing bricks, thermal insulation layers and water-absorbent layers. Water slag is formed by rapidly cooling molten blast furnace slag in water. There are two main methods which are water quenching in the slag pool and water quenching in front of the furnace.

Water slag is used as building materials in the production of cement and concrete. Since water slag has potential hydraulic gelling properties, it can be used as a high-quality cement raw material under the action of activators such as cement clinker, lime, and gypsum. Water slag can be made into slag Portland cement, gypsum slag cement, lime slag cement, slag bricks, slag concrete, etc. It can also be used as a raw material for the production of environmentally friendly cement bricks.
