U.S. Slag Cement Shipments
The use of slag cement provides substantial environmental benefits by replacing a portion of portland cement in concrete and other construction applications. Slag cement – a product recovered from a blast furnace during iron production – substantially lowers the embodied energy and emissions in concrete and reduces the amount of virgin material needed to produce concrete. The 3.4 million metric tons of slag used in 2007 (slag as a separate product and slag used in blended cements) represents the following environmental benefits:
*Blended cement containing slag cement includes ASTM C595, Types IS, IT(S<70), and IT(S≥70).
