Micro Silica

Detailed Product Description

We are the large supplier for undensified and densified micro silica (silica fume ) used for concrete and refractory industry (SiO2: 85%-97%) .Especially we supply you according your special requirements .

Silica fume in concrete

Characteristics of Silica Fume
- Significantly enhanced compressive strength
- Significantly reduced permeability
- Improved corrosion resistance
- Improved pumpability
- Improved cohesion/resistance to segregation
- Improved adhesion
- Improved abrasion resistance
- Increased electrical resistivity
- Improved resistance to most sulphates and various other forms of chemical attack.

Applications for Silica Fume
Marine concrete
- High strength concrete
- Concrete subjected to aggressive groundwater conditions
- Chemical plants
- Industrial floors subject to high abrasion levels
- Dams and spillways for strength and abrasion resistance
- Shotcrete, for reduced rebound, and improved cohesion/adhesion
- Grouts and mortars/Repair concrete
- Jobs requiring long pump lines
- Watertight basements.

Silica fume in refractory

Enhancing the fluid of pouring refractory, reducing the volume of used water, be easy to shape, and raising the production efficiency.
Because of its untramicrostructure for gap filling, the compact and intensity of refractory gain rising by a wade margin.
Silica fume is a highly effective pozzolanic material, so it's easy to come into being Mullite Phase, under the premise that Al2O3 exists, enhance elevated temperature strength and thermal shock of refractory.
