Slag

Blast Furnace Slag is produced as a by-product during the manufacture of iron and steel. The Slag is then further processed to produce Granulated Blast Furnace Slag (GBFS) and Ground Granulated Blast Furnace Slag (GGBFS). Slag possesses latent hydraulic properties which enhance most durability properties when blended in cement and concrete.

See below for more information.

Granulated Blast Furnace Slag

Granulated Blast Furnace Slag has a glassy structure and can be used as a fine aggregate or binder.  GBFS is commonly used in the manufacture of blended cements where it is inter-ground or blended separately with cement usually at a 20% - 40% proportion.  Unblended GBFS is can be used in road pavements and building products.

Ground Granulated Blast Furnace Slag

GGBFS is a supplementary cementitious material when used in concrete.  It enhances a range of concrete performance characteristics such as the reduction of the heat of hydration in mass concrete pours, reduces the permeability of concrete and improves the durability properties of concrete in resistance to aggressive environments.  In NSW Cement Australia markets GGBFS under the brand Ecocem.
