Granulated Blast furnace slag (GBS) is a light coloured 0/4mm glassy sand produced by the rapid quenching of molten blast furnace slag using large volumes of water. Production and Processing. GBS or Granulate as it is sometimes known is produced by rapidly cooling molten Blast furnace slag with water as the slag is tapped from the furnace.
GBFS is ground to a suitable fineness to produce Ground Granulated Blast Furnace Slag (GGBFS), which is used as a cementitious material in concrete to enhance long-term performance and durability characteristics while reducing life-cycle and maintenance costs.
Ground granulated blast furnace slag is produced by pulverizing granulated blast furnace slag produced by blast furnaces as a by-product of the iron-making process. This hydraulic admixture is popular for use as raw material for Portland blast furnace slag cement, admixture for raw concrete, and other applications.
Ground granulated blast furnace slag (GGBS) GGBS is primarily a binder used as an addition to cement which uses the latent hydraulic properties of GGBS to produce Portland blastfurnace cement (6-35% of GGBS) or blastfurnace cement (36-90% GGBS) produced by blending at the concrete mixer, or as a factory blend at the cement factory.
