As cement industries can utilise slag as an input to their production process, Indonesia Cement Association (ASI) and cement industries are one of the most vital stakeholders.

Steel slag aggregate (SSA) is a byproduct of the production of steel in an electric arc furnace. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense (SSA is 2030% heavier than naturally occurring aggregates such as basalt and granite).

Since then two more detailed Guides have been produced relating to specific areas of slag usage: A Guide to the Use of Iron Blast Furnace Slag in Cement and Concrete (1997),and A Guide to the Use of Steel Furnace Slag in Asphalt and Thin Bituminous Surfacings (1999)

May 09, 2018· Ground Granulated Blast Furnace Slag concrete. GGBS hardens very slowly so it is generally used along with ordinary Portland cement in concrete. A typical combination is 50% GGBS and 50% ordinary Portland cement. But percentages of 20 to 80 are commonly used. Greater the percentage of GGBS, greater will be the effect of GGBS in concrete.

Slag cement is the byproduct of steel production. It is formed by the molten slag in blast furnaces used to process iron ore to make steel. Finely ground limestone can replace 5% to 15% of portland cement. Portlandlimestone cements require less energy to produce because the limestone is not pyroprocessed like the portland cement it replaces.

Slag Cement, formerly referred to as ground, granulated blastfurnace slag, is a glassy, granular material formed when molten, iron blastfurnace slag is rapidly chilled typically by water sprays or immersion in water and subsequently ground to cement fineness. Slag cement is hydraulic and can be added to cement as an SCM.
