Cement
Granulated Blast Furnace Slag (GBFS) is one of the waste material groups obtained from various metallurgy plants. In production of raw iron, blast furnace slag remains above raw iron due to having less weight and iron ore gangue is composed at a temperature between 1,400 to 1,600 °C after burning of coke and limestone.
