TJSW® GBFS & GGBFS

●     Granulated Blast Furnace slag (GBFS) is a by-product from the iron making process. It is produced when smelting iron ore in a blast furnace to separate iron from the minerals present in the ore. The hot slag molten liquid to be cooled or quenched by water very rapidly from about 1400°C-1500°C, to minimise crystallisation and to produce amorphous (or glassy) slag. The rapid cooling associated that creates a granular glassy material which gives blast furnace slag its cementitious properties.

In addition to the mineral fraction of the ore, it also contains the minerals added as process additions in the blast furnace, in particular limestone or dolomite. The chemical composition of blast furnace slag is close to the one of clinker.

 

 

●   Ground Granulated Blast Furnace slag (GGBFS) is formed when GBFS is further processed and ground to a suitable fineness.
