Ground Granulated Blast Furnace Slag - an overview ...

11.2.2 Ground-granulated furnace slag. Ground granulated blast-furnace slag, GGBFS, is a by-product of iron in blast-furnace. It mainly consists of silicate and aluminosilicate of melted calcium that periodically needed to be removed from the blast furnace. Similar to fly ash, the chemical compositions of GGBFS depend on the row materials used ...
