CEMENT RAW MATERIALS - International Cement Review

Oct 12, 2020· Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag must first be separated from the molten iron.
