You can buy high quality Micro Silica CL*2 at silica-powder.com,
which it is the high performance admixture for concrete and
construction.
1. What is Micro Silica
Microsilica (Or silica fume, Silica powder) is a byproduct of
producing silicon metal or ferrosilicon alloys.
Mine electric furnace generates mass very reactive SiO2 and Si gas.
The gas was oxidation and condensation precipitation with air
rapidly.
2. Micro Silica Features
* High early strength
* Greater impermeability
* High ultimate compressive strengths
* Substantially greater resistance to corrosion
3. Densified Micro Silica in Concrete Performance
A. Micro silica is used in high performance concrete
Can prevent concrete from the corrosive chloride and seawater
Improving the high resistivity of concrete
Improving the wear resistance of building, like flight runway,
aircraft carrier deck, high speed way
Can improve strong chemical corrosion resistance
B. Micro silica is used in high intensity concrete
Improving the compressive strength of concrete to **0MPa
Improving the modulus of elasticity of concrete to ****0MPa
Can make the flexural strength of flight runway to *4MPa with
*8days
Apply for projects and precast assault with high early strength
C. Micro silica is used in shotcrete concrete
Reducing the shotcrete rebound rate loss to *0%
Improving the construction efficiency, one sprayed layer thickness
up to *2inch
Strength the resistivity and lower the permeability
Can retain compressive strength and flexural strength
