micro silica/silica fume

Densified Powder&Grain Microsilica Bulk Density:550-700kgs/m3

 Microsilica. silica fume  concrete in the application

1,Manufacture high-strength concrete (C70 above), significantly enhanced the strength of concrete and pumping performance; 2,Manufacture of high permeability (≥ P30), waterproof concrete structure for the MTR, tunnels, the basement of high-rise buildings;  3,Manufacture marine and chemical concrete, because of its dense high performance, effectively prevent the sulfate and chloride ion permeability of concrete, erosion, avoid being reinforced concrete corrosion, thereby prolonging the life span of concrete; 4,Highway, bridge projects, the basic needs not only of concrete indicators, its wear and erosion resistance is very demanding, micro-doped silica fume is necessary; 5,micro-silica fume 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 Pit Support for the high-strength concrete plus jet ; underwater construction projects (such as: Pier dam, and drilling platforms, etc.) used in concrete admixture
