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.
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
- European Code: 19.12.01
- Basel Code: B1010
- HS Code: 2619.0020
- Quantity: 2000 tons currently available
- Monthly quantity: 500-1000 tons depending on production
- Size: 350 1200 mm
- Fe content: from 77 to 86%
- C content: above 2,5-3%
- Bulk density: 2,8-3,4 tons/m3
- Loading type: loose in 20 (26-27 tons on average)
The level of Fe% in the slag has been estimated by water displacement test. For any further information please feel free to contact us
This Cast Iron slag is a by-product derived from the production of thermal insulating products. The byproduct is a ferrous slag which can be utilised in an electric arc furnace to produce crude steel.

Silica Sand * Silica Sand is a type of sand usually available in the form of quartz. It is a hard and crystalline form of mineral components. * Silica sand is the most abundant mineral with the purity more than 99.0%. It is the preferred choice of consumption for various industrial purposes.
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
