Micro Silica

We offer high quality microsilica with grade 92% sio2, it is the ideal admixture in high performance concrete, high intensity concrete, shotcrete, reinforced concrete, premixed concrete, blast furnace cement, cement portland and etc.
1. 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. 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.,
3. Microsilica is used in high performance concrete
for improving the intensity and durability, more and more people are widely applying microsilica in high performance concrete for national infrastructure. High performance concrete with microsilica additive turn out strong toughness, higher antifreeze, wear resistance, chemical resistance, extend the life of the building and reducing the maintenance and testing cost. In recent year, there are uncommon examples of destroyed and collapsed bridges and piers. Most of them are severe erosion caused by sea.
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
4.
Microsilica is used in high intensity concrete
make the building designer more creative project optional with microsilica additive in high intensity concrete. For example, with microsilica additive in high intensity concrete will avoid many pillar in high-rise building design and then increase the using space of building and make greater span prestressed beams.
