blast furnace slag (GGBFS). Iron slag and steel slag are used primarily as aggregates in concrete (air -cooled iron slag only) and as asphaltic paving, fill, and road bases; both slag types also can be used as a feed for cement kilns. Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements.
