The Ground Granulated Blast Furnace Slag (GGBS/GGBFS) is a type of eco-friendly green building material and high quality secondary cementitious material for concrete and cement. It is recognized as one of the best secondary cementations material for building high durable concrete stricture in the world today! GGBS has taken over a top place of high-performance cement and concrete mineral additives with its unique characteristics of hydration, low-price raw material. GGBS is obtained by quenching molten iron blast furnace slag (a by-product of iron and steel making) in water or steam. It is then further grounded into the desired fineness in terms of the required particle size distribution. The main components of blast furnace slag are CaO (30-50%), SiO2 (28-38%), Al2O3 (8-24%), and MgO (1-18%). The other important aspect of GGBS is its superiority in concrete durability which extends the lifespan of buildings from fifty years to a hundred years.

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.

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.
The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree Celsius. The process is carried out in a blast furnace. The formation of GGBFS is not direct. The by-product of iron manufacturing is a molten slag and molten iron. The molten slag consists of alumina and silica, also with the certain amount of oxides. This slag is later granulated by cooling it. For this, it is allowed to pass through a high-pressure water jet. This result in quenching of the particles which results in granules of size lesser than 5mm in diameter. The main constituents of blast furnace slag are CaO, SiO2, Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further dried and ground in a rotating ball mill to form a fine powder, known as ground granulated blast furnace slag cement. Now different methods can be employed to perform the main process called as the quenching.
Applications & Benefits of GGBFS:
In concrete:
The incorporation of ground granulated blast furnace slag in concrete manufacture gains many advantages which are mentioned below:
GGBFS in concrete increases the strength and durability of the concrete structure.
It reduces voids in concrete hence reducing permeability
GGBFS gives a workable mix.
It possesses good pumpable and compaction characteristics
The structure made of GGBFS constituents help in increasing sulphate attack resistance.
The penetration of chloride can be decreased.
The heat of hydration is less compared to conventional mix hydration.
The alkali-silica reaction is resisted highly.
These make the concrete more chemically stable.
Gives good surface finish and improves aesthetics.
The color is more even and light.
Lower chances of efflorescence.
The maintenance and repair cost of structures are reduced thus increasing the life cycle of concrete structures.
Unlike cement, GGBFS does not produce carbon dioxide, sulphur dioxide or nitrogen oxides.
White Cement:
White Portland Cement is of high quality, whiteness and strength, it essentially has the same properties and characteristics as gray cement, except for color.
It is widely used in numerous applications such as precast concrete, cast-in-place concrete, terrazzo, median barriers, curbs, tile grout, paint, masonry units, swimming pools, glass fibre reinforced surface bonding mortars.
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.

Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500�°C. When iron-ore, coke and limestone melt in the blast furnace, two products are producedâ??molten iron, and molten slag. The molten slag is lighter and floats on the top of the molten iron. The molten slag comprises mostly silicates and alumina from the original iron ore, combined with some oxides from the limestone. The process of granulating the slag involves cooling of molten slag through high-pressure water jets. This rapidly quenches the slag and forms granular particles generally not bigger than 5 mm. The rapid cooling prevents the formation of larger crystals, and the resulting granular material comprises around 95% non-crystalline calcium-alumino silicates. The granulated slag is further processed by drying and then grinding in a vertical roller mill/rotating ball mill to a very fine powder, which is GGBS.
Copper slag is a low cost expendable abrasive suited for open blast cleaning and due to its low silica content it does not pose the health hazards created by silica sand. Its sharp, hard particles can provide a fast cleaning action and an excellent surface profile. It is available in various sizes
Copper slag is abrasive blasting grit made of granulated slag from metal smelting processes (also called iron silicate). Copper slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-2 and SA-2. Copper slag blasting media/grit is manufactured of the granulated slag of copper refineries, and used for blast-cleaning of metal surface. In different industries it is called different names abrasive powder, grit, copper slag grit, mineral grit, grinding grains, etc.
