A Comprehensive Review on the Ground Granulated Blast Furnace Slag

When limestone, iron ore and coke are melted together in a blast furnace, iron and slag are created in the molten state. When the slag from the blast furnace is molten, it is swiftly cooled with strong water jets, which transform it into GGBS, a fine, granular and glassy substance. Figure 2 depicts the GGBS manufacturing process.
