Granulated blast furnace slag is a raw material for the production of cement. When the pig iron is smelted in the blast furnace, the obtained fused material mainly containing silicate and aluminosilicate is quenched and granulated to obtain granulated blast furnace slag. Granulated blast furnace slag, formed by melting slag from blast furnace iron-smelting, is mostly formed without time to crystallize.
Granulated Blast Furnace Slag (GBFS) is a valuable by-product of steel manufacturing. Iron is extracted from iron ore, which takes place in a blast furnace where the ore, limestone or dolomite, and fuel (coke) are introduced into a furnace to assist the separation of the molten iron from the impurities. When taken out of the blast furnace, slag is in a molten condition.
Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components iron and molten slag.
By using granulated blast furnace slag, consumption of limestone, the main raw material of cement is reduced by approximately 40%. Also, you can omit the calcinating process of limestone reducing energy consumption by approximately 40%. These factors result in reducing CO 2 emissions produced during the manufacturing process by approximately 42%.
