production of its by-product blast furnace slag. Similarly, steel cannot be prepared in the Basic Oxygen Furnace (BOF) or in an Electric Arc Furnace (EAF) without making its by-product, steel slag [7]. The use of steel slag aggregate in concrete by replacing natural aggregate is a most promising concept [4].
