Bemsun Densified Microsilica Admixture for Concrete Cl93

BEMSUN offer high quality microsilica with grade 92% SiO2, it is the ideal admixture in cement, 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.
Performance:
Improving the compressive strength of concrete to 140MPa
Improving the modulus of elasticity of concrete to 40000MPa
Can make the flexural strength of flight runway to 14MPa with 28days
Apply for projects and precast assault with high early strength
5. Microsilica is used in shotcrete concrete
They are applying for solid rock projects; Mining tunnel lining; Column offshore projects. Make it with good adhesion and not only reducing the rebound in wet and dry environment, but also make fineness degree suit variety of vents and then save more cost and time and effectively.
Performance:
Reducing the shotcrete rebound rate loss to 50%
Improving the construction efficiency, one sprayed layer thickness up to 12inch
Strength the resistivity and lower the permeability
Can retain compressive strength and flexural strength
