application of microsilica for concrete in engineering construction-pg电玩城

introduction highway construction: taking full advantage of the dry strength, high strength and abrasion resistance of the microsilica concrete, it can build high-grade highways, airport runways, highway tunnels and road surface repair projects. yizheng chemical fiber company built roads with microsilica concrete on the main road of the center of the factory. the compressive strength reached 25mpa in 12 hours, and the abrasion resistance doubled. the compressive strength reached 37 mpa in 24 hours, exceeding the designed cl20 concrete.

port, bridge and salt water engineering: the micro-silicon powder concrete has high density and high resistivity, which is not easy to form electrochemical damage and enhances the anti-rust performance. the tsing ma bridge in hong kong, the timber pier in lianyungang, jiangsu province, and the yangtze river bridge at the great buddha temple in chongqing are examples of successful applications.

the concrete project of mixed shotcrete: after adding micro-silicon powder into the concrete, the adhesive performance and cohesion of the plastic concrete were improved, the resilience was greatly reduced, the thickness of the first forming of shotcrete was increased, the construction period was shortened, and the project cost was saved. in europe and the us, 75 per cent of shotcrete is made with microsilica, while in norway and sweden it is a necessary ingredient for shotcrete.

hydro-electric engineering: hydraulic structures such as dam entrance sluice, diversion channel, tunnel, pressure regulating well, lower structure of main plant (especially the volute of water machine), etc., make full use of silicon-powder concrete with good waterproof, anti-seepage, anti-scrubbing and anti-cavitation characteristics. since 1982, it has been widely applied in the repair and maintenance projects of gezhou dam, three gorges, qinghai-tibet railway, dahuofang reservoir, yingxiu bay power station and longyangxia power station in changqing oilfield. at present, the application of micro-microsilica concrete in ertan power station, zipingpu water control project, south-to-north water transfer project and xiaolangdi water control project in yellow river has also achieved good results.

introduction of engineering and civil engineering: microsilica concrete has the characteristics of drought and high strength, which is widely used in industrial plants and high-rise buildings. such as liaoning anshan international hotel c50 concrete, beijing tax building c110 concrete. it can increase the strength, reduce the size of the construction section, shorten the construction period and save the engineering cost.
