Bemsun manufacture high bulk density silica metal fume grade*2 and will provide you the favorable competitive price of silica metal fume. 

1. What is silica metal fume

Silica metal fume (Or silica fume, micro silica) 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. Silica metal fume Features

* High early strength

* Greater impermeability

* High ultimate compressive strengths

* Substantially greater resistance to corrosion



3. Silica metal fume performance in Concrete

A. silica metal fume 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. silica metal fume 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. silica metal fume 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
