What is Microsilica
Microsilica or Silica Fume, which it is made from the oxidized silicon vapor of silicon iron or element
silicon with special dust catcher and final turn out amorphous SiO2 powder.
Average particle size of Microsilica is around 0.*5~0.*0μm, specific area is ****0~****0m 2 /kg, and they are with
Strong surface activity.
The main element of Microsilica is amorphous SiO2. Besides, the burner gas accompanies impurity. Like dissociate
C, Fe2O3、CaO、K2O、Na2O and etc. The Microsilica Color along with the higher content of C、Fe2O3, the deeper
color is changed from White-Grey White-Grey-Deep Grey.
By directly collected Microsilica from burner is named Original Micro silica. The bulk density is around **0~**0kg/m3.
But for the convenience transportation and application, the Original Microsilica can be increased bulk density.

Main Features:
* High early strength
* Greater impermeability
* High ultimate compressive strengths
* Substantially greater resistance to corrosion

Microsilica Applications:

1. Microsilica is used in high performance concrete, improving the intensity and performance of concrete and extend the concrete life.
2. Microsilica is used in dry mortar, grouting concrete, improving intensity
3. Microsilica is used in durable floor, increasing flowabiliy, improving anti-corrosive
4. Microsilica is used in cement, improving the quality than common cement
5. Microsilica is used in chemical fertilizer and prevent it from caking
6. Microsilica is used in silicate brick
7. As a additive material for resin and another high polymer material and subsitute for black,
silicon dioxide, talc stone, asbestos, steam solvent and tec
