Chapter 1 Ground Granulated Blast-Furnace Slag
Blast-furnace slag (bfs) is a by-product in the manufacture of pig iron in the blast furnace. It forms by fusion of the gangue, i.e. non-ferrous material of the iron ore, mainly silica and alumina compounds, with calcium and magnesium oxides of the thermally decomposed carbonatic flux and combustion residues of the coke.
