Slag

Definition: granulated blast-furnace slag that has been finely ground and that is hydraulic cement.- ACI Concrete Terminology


The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas emissions, and reduced use of raw materials. Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast furnace. - Air-cooled blast-furnace slag—The material resulting from solidification of molten blast-furnace slag under atmospheric conditions; subsequent cooling may be accelerated by application of water to the solidified surface. - Expanded blast-furnace slag—The lightweight, cellular material obtained by controlled processing of molten blast-furnace slag with water or water and other agents such as steam, compressed air, or both. - Granulated blast-furnace slag (GBFS)—The glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water. - Ground-granulated blast-furnace slag (GGBFS)—Now known as cement, slag—granulated blast-furnace slag that has been finely ground and that is a hydraulic cement.
