Microsilica silica fume concrete in application

1. Manufacture high-strength concrete (C70 above) significantly enhanced the strength of concrete and pumping performance
2. Manufacture of high permeability (P≥30) waterproof concrete structure of 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 be3ing reinforced concrete corrosion , thereby prolonging the life span of concrete
4. Highway-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.
