slag. In the case of pig iron production the flux mostly contains a mixture of limestone and forsterite or in some cases dolomite. In the blast furnace the slag floats on top of the iron and is poured for separation. Slow cooling of slag melts results in an unreactive crystalline material consisting of Ca-Al-Mg silicates.

Ground Granulated Blast Furnace Slag Conclusion

Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.
