Crushed Blast Furnace Slag
Jan 10, 2014 Slags are one of the most natural products of all. Slags are principally divided into blast furnace slag and metallurgical slag. At voestalpine the slags resulting from the steelmaking process are separated into blast furnace and metallurgical slags and then recycled. The separated slags are processed into valuable products.Blast furnace slag, either crushed in situ or as plant crushed graded macadam, has become increasingly important as a base or sub-base on heavily trafficked roads in the Newcastle, Sydney, Wollongong region. The material predominantly used has been air-cooled slag which is considered to have self stabilizing action but at a level too weak to be.

Most lightweight aggregate is produced from materials such as clay, shale, or slate. Blast furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes, however. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of .The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 , a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron. In the case of inferior grade ores below 60.
