Description

Microsilica is the Concrete admixture, it play a good performance in concrete construction. It is the 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.

Concrete Admixture Microsilica , build a durable future into the infrastructure of seaport, high building, reservoir dam, Railway, driver road, bridge, metro, tunnel, airport runway, coal lane and etc.


1. Microsilica performance in concrete 



a. microsilica admixture is usd in in high performance concrete



Performance:

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. Microsilica admixture is used in high intensity concrete



Performance:

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. Microsilica admixture used in shotcrete concrete



Performance:

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
