Slag Aggregate - an overview ScienceDirect Topics

Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3, or dolomite, CaCO 3 MgCO 3) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form the non-metallic blast furnace slag.
