This method has been used to a moderate extent in Germany. It isnecessary to pass the granulated slag under a strong magnet in order to remove any particles of metallic iron. Blast-furnace slag is used in making-four classes of cement—.Puzzolan, orordinary slag cement, usually simply called slag cement.

According to the Slag Cement Association, an industry trade group, incorporating slag cement as a supplement in concrete offershigher strength,reduced permeability and improved resistance to chemical attack. And as a recycled material, its production requires far less energy and natural resources than the conventional cement it partially replaces.

Ground granulated blast furnace slag(GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. GGBFS is divided into three classifications based on its activity index. Grade 80 has a low activity index and is used primarily in mass structures because it generates less heat than portlandcement.
