Micro silica

product name :Micro silica 1.By-product of the ferrosilicon and silicon metal industry 2.Very high specific surface area 3.Very high content of amorphous silicon dioxide 4.Very efficient filler 5.Very reactive pozzolan Microsilica silica fume concrete in application Manufacture high-strength concrete (C70 above) significantly enhanced the strength of concrete and pumping performanceManufacture of high permeability (P≥30) waterproof concrete structure of MTR, tunnels, the basement of high-rise buildingsManufacture marine and chemical concrete, because of its dense high performance, effectively prevent the sulfate and chloride ion permeability of concrete , erosion, avoid be3ing reinforced concrete corrosion , thereby prolonging the life span of concreteHighway-bridge projects, the basic needs not only concrete indications, its wear and erosion resistance is very demanding, micro-dopted silica fume is necessary. Microsilica fume has strong activity, a caustic water properties, applicable to the needs of rapid construction early strength, high strength concrete admixtures, tunnels, subways, large-scale structure in the course of construction fit for the high-strength concrete plus jet, underwater construction projects, etc used in concrete admixture. Packaging Microsilica is supplied in a range of packagings: 800 900kg jumbo PP bag with PE liner The Jumbo bag conforms to GB/T10454 and EN ISO 21898 with UV-proof function and anti-aging character. 25kg woven bags with PE liner; 25kg paper bags 10kg water-degradable paper bags;
