What is Slag Cement? (with pictures)

Feb 07, 2021  A. B. Kelsey Date: February 07, 2021 Slag cement was first used commercially in Germany in the 1860s.. 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
