Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
GGBFS Ground granulated blast furnace slag (GGBFS) 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.

Packing: Loose in container Loading: in 20 Container For further information, please feel free to contact us.
We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
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.

Silica is mainly used as a carrier of agricultural chemicals. Finely crushed silica powder is coated with agricultural chemicals and sold on the market for agricultural use. Silica itself has no effects; it merely serves as a carrier, and so can be dispersed without affecting the farmland, which makes it advantageous as a core material. It's used as Fire-resistant product powder, Agricultural chemical carrier, Agricultural chemical carrier, Construction board
