Introduction of slag cement Cement Science

Blast-furnace slag (BFS) is formed from a liquid at 1350-1550 C during the manufacture of iron. When reaching the bottom of the furnace, the liquid slag forms a layer on top of the molten iron due to its lower density. Being separated from the molten iron, the liquid slag is cooled in the air or with water.
