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 woodchips.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.

 

 

 

 

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 

 

 

 

 

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.

 

 

 

 

 

 

 

 

 

 

 

WINITOOR was established in 2004 in Quanzhou Fujian Province of China.We are specialized in the R&D.production and marketing of a series of building material: microsilica(silica fume) ,water reducing agent... they are in the application of concrete(HPC), Mortar ,Refractory,etc. We have built our own microsilica processing plant in the major area of Chinese ferro-silicon and silica metal factories,and our annual output is more than 50000 metric tons.
