What is slag cement or ground granulated blast-furnace ...

Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is hydraulic cement. When slag cement is mixed with water, however, the initial hydration is much slower than portland cement mixed with water; therefore, portland cement or salts of alkali metals, principally sodium and potassium or lime, are used to increase the reaction rate of slag cement (ACI 233R).

Ground Granulated Blast Furnace Slag

Ground granulated blast furnace slag (GGBFS) is designated in ASTM C 989 and consists mainly of silicates and aluminosilicates of calcium. GGBFS is divided into three classifications based on its activity index. Grade 80 has a low activity index and is used primarily in mass structures because it generates less heat than portland cement.

Ground granulated blastfurnace slag - Concrete

Ground granulated blastfurnace slag. Ground granulated blastfurnace slag (GGBS) is the slag from iron producing blastfurnaces that is rapidly quenched in water and then ground into a powder. Chemically it is similar to, but less reactive than, Portland cement (PC). When mixed with water it will hydrate in a similar way to Portland cement.

What is slag cement

Slag cement, or ground granulated blast furnace slag (GGBFS), has been incorporated into concrete projects in the U.S. for over a century to improve durability and reduce life cycle costs. Among its measurable benefits in concrete are better workability and finishability, higher compressive and flexural strengths, and improved resistance to aggressive chemicals.

When Ground Granulated Blastfurnace Slag is blended with cement or added to the concrete mixer the amount of soluble SO3 and C3A is reduced in proportion to the slag added. While we are not aware of any difficulties in setting times or admixture performance we advise comprehensive mix trials especially at high slag replacement levels to check workability.
