1.2.1. Ground granulated blast furnace Slag: It is hydraulic type of SCM. Ground granulated blast furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag,a by-product of iron and steel making from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

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.
