Granulated blast-furnace slag (GBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) into water from a blast furnace in water or steam, to produce a glassy, granular product. The chemical composition of a slag varies considerably depending on the composition of the raw materials in the iron production process.
(2) The production of expanded blast furnace slag is no longer favored and is being replaced by the pelletizing procedure. ACBFS has been used as an aggregate in Portland cement concrete, asphalt concrete, concrete, asphalt and road bases. Pelletized blast furnace slag has been used as lightweight aggregate and for cement manufacture.
