Amorphous Silica or Silica Dust for High Quality Microsilica Properties

Product Detail

  Product Description:                  





Micro silica ,also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and wood-chips.The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2),its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface active.



for precast concrete with SGS testing


  Features Characteristics:           




1).Appearance is as grey&white off.

2).High electrical resistivity

3).Low Permeability

4).Superior resistance to chemical attack from chlorides,acids and sulfates

5).Low chloride ion diffusion

6).High reactive Pozzolan

7).High temperature strength

8).Improved stability ingeothermal environment 




 Microsilica in application of concrete            




1)Manufacture high-strength concrete(C79 above),Significantly enhanced the strength of concrete and pumping performance;

2)Manufacture of high permeability(=P30),waterproof concrete structure for the MTR,tunnels,the basement of high-rise buildings;

Manufacture marine and chemical concrete,because of its dense high performance,effectively prevent the sulfate and chloride ion permeability of concrete, erosion, avoid being reinforced concrete corrosion,theereby prolonging the life span of concrete; 

3)In water highway,bridge project, the basic needs not only of concrete indicators, its wear and erosion resistance is very demanding, micro-doped silica fume is necessary;

4)MICROSILICA fume strong activity, a caustic water properties,applicable to the needs of rapid construction early strength,high strength concrete admixtures;tunnels,subways,large-scale structure in the course of construction Pit Support for the high-strength concrete plus jet; underwater construction project (such as: Pier Dam,and drilling platforms,etc) use in concrete admixture.




 Application area:                         




1) Concrete or Shotcrete

• Increase its density and strength, improve the performance on its durability,

impact resistance, corrosion resistance, anti-permeability and frost resistance etc

2) Refractory material & Ceramics material

• Greatly improve its density, strength and high temperature performance.

3) Cementitous Repair Products (Mortars & Grouts)

• Low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc

4) Oil Well Grouting

• Increase durability and compressive strength, decrease permeability, better control of gas leakage

5) Concrete Tile, roofing & wallboard,panels

• Lightweight and improve the strength

6) Polymers & rubber product

7) other application, such as waterglass industry, thermal insulation material etc.
