sulfur, iron, manganese and other trace elements. Air-cooled slag, which is allowed to solidify slowly in ladles or pits, is by far the most abundant and is a rock-like material which is almost wholly crystalline [2]. Blast-furnace slag aggregates gen-erally have desirable properties such as soundness, strength, shape, abrasion resistance and ...
