Granulated Blast Furnace Slag or GBFS is formed when Blast Furnace Slag or BFS is successively at a fast rate quenched from the furnace rather than left for cooling. It has a density of about 60% to 70% that of natural sand. This material has a much increased resistance to sulfate attack.
This eventually leads to better performance in countering acids of any type. In GBFS, no type of reaction related to alkali and silica occurs. Also the material provides a huge saving in connection to carbon dioxide emission which is an extra boon. What constitutes GBFS are its properties that consist of durability, appearance, higher ultimate strength than concrete which is made up of Portland cement and high sustainability level of the product made out of this material.
Blast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production. The average chemical composition of the material is the following: CaO 36.50% MgO 7.90% Al2O3 11.70% MnO 1.13 % K2O 0.43 % Na2O 0.22% FeO 1.71 % SiO2 38.73% TiO2 0.69% S 0.86% We have available two different lots of slag GRANULATED BLAST FURNACE SLAG The granulated blast-furnace slag is sand-type slag manufactured by spraying high-pressure water jets on a blast-furnace molten slag.
Origin :- Vietnam . India
About THE Product :
Blast furnace slag is used in the production of cement (iron Portland and blast furnace cement).
Air-cooled blast furnace slag is formed by allowing the molten slag to cool relatively slowly under ambient conditions; final cooling can be accelerated with a water spray. The cooled material is hard and dense, although it can have a vesicular texture with closed pores. After crushing and screening, air-cooled slag can be used in several applications.
Granulated slag is formed by quenching molten slag in water to form sand-sized particles of glass. The disordered structure of this glass gives the material moderate hydraulic cementitious properties when very finely ground into granulated blast furnace slag, but if it can access free lime, the granulated blast furnace slag develops strong hydraulic cementitious properties.
Pelletized or expanded slag is cooled through a water jet, which leads to rapid steam generation and the development of innumerable vesicles within the slag. The vesicular texture reduces the overall density of the slag and allows for good mechanical binding with hydraulic cement paste.
Blast Furance Slag is a nonmetallic co-product which is produced in the process of iron manufacturing, Granulated Blast Furnace Slag is a glassy granular material formed when molten blast furnace slag is rapidly cooled by direct water.
Rapid cooling prohibits the formation of crystals and forms glassy, non-metallic, silicates and alumino silicates of calcium.

Desulphurisation Slag is an iron slag derived from the desulphurisation skimming process. This material is an iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si), but has a stable chemistry with 75 -80% chemistry.
The level of Fe% in the slag has been estimated by water displacement test.
This material con offer competitive advantages respect other metal scraps:
Price;
Stable Chemistry;
The material can be loaded loose in 20 heavy duty container.
We are proposing about 2000tons of iron slag derived from the desulphurisation skimming process. This material is a iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si). In order to enhance its usability, the material is processed and screened. We can propose two specifications of Iron Slag
