Granulated Blast Furnace Slag - an overview,
The presence of a competitive and efficient supply chain is essential for the successful scale-up of geopolymer technology. For instance, granulated blast furnace slag (GBFS) is produced during the production of pig-iron. Although there is a risk that production methods for pig-iron will change and reduce the availability of GBFS, this is not currently viewed as a substantial risk. AsGround Granulated Blast Furnace Slag - an overview,,Ground granulated blast-furnace slag, GGBFS, is a by-product of iron in blast-furnace. It mainly consists of silicate and aluminosilicate of melted calcium that periodically needed to be removed from the blast furnace. Similar to fly ash, the chemical compositions of GGBFS depend on the row materials used in the production of iron while the physical properties depend on theGround Granulated Blast Furnace Slag (GGBS) | Chemical,,09/05/2018· Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material.

The most common process is quenching with water, but air or a combination of air and water can be used. When the liquid slag is cooled and solidified by rapid water quenching to a glassy state, little or no crystallizationSTABILIZATION OF SOFT SOIL WITH GRANULATED BLAST,of these waste products prior to use. The present paper evaluated the potential of granulated blast furnace slag (GBS) with fly ash to stabilize a soft soil.
