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 blast-furnace slag - Wikipedia

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

Ground Granulated Blast Furnace Slag (GGBS) - JSW Cement

Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement).

Common Uses for Slag | National Slag Association

Molten slag is generally placed into ground bays for cooling. Both BOF and EAF slags are somewhat heavier than Blast Furnace Slag and most quarried rock material. Uses include. Blending with many other products such as granulated slag, fly ash and lime to form pavement material, skid resistant asphalt aggregate and unconfined construction fill.

Granulated Blast Furnace Slag -

Granulated phosphorus slag is a latent cementitious material but less reactive than granulated blast-furnace slag at early age due to the lower Al 2 O 3 content and the presence of P 2 O 5 and F. A hydraulic index of phosphorus slag is defined as follows (Shi et al., 2006; RCT 5024-83, 1983):

"Ground Granulated Blast Slag (GGBS) In Concrete – A Review"

Ground Granulated Blast furnace Slag (GGBS)[1] is a by product from the blast furnaces used to make iron. These operate at a temperature of about 1500 degrees centigrade and are fed with a carefully controlled mixture of iron ore, coke and limestone. The iron ore is reduced to iron and the remaining materials from a slag

Processing of Granulated Blast Furnace Slag and its ...

Typically, granulated slag is ground to an air-permeability (blaine) fineness exceeding that of Portland cement to obtain increased hydraulic activity at early ages. As with Portland cement and pozzolans, the rate of reaction increases with the particle fineness. Ground Granulated Blast Furnace Slag (GGBFS) is activated by alkalis or Ca(OH)2 etc.
