Slag

Slag

Ground-granulated blast-furnace slag (GGBFS) is produced by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder.

When added to concrete, GGBFS enhances a range of performance characteristics such as the reduction of the heat of hydration in mass concrete pours, reduction of concrete permeability and improvement of durability properties in resistance to aggressive environments. Similar to fly ash blends, early age strength development of slag blends is slower than straight cement concrete however strength development from 28 days onwards is equivalent or better.

In NSW, Cement Australia markets GGBFS under the brand Ecocem.
