GGBFS is a byproduct of the iron and steel industry, specifically from the production of iron in blast furnaces. It is obtained by rapidly quenching molten slag from the blast furnace with water or steam, which results in the formation of glassy granules. These granules are then ground into a fine powder, which is GGBFS.
