microsilica mainly acts on which engineering construction fields-pg电玩城

specific application of mcrosilica in the following engineering construction fields:

1. water conservancy and hydropower projects: hydraulic structures such as dam entrance sluice, water diversion channel, tunnel, pressure regulating well, lower structure of main plant (especially water machine volute), etc., make full use of silicone-powder concrete, which has good waterproof, anti-seepage, anti-scrubbing and anti-cavitation characteristics. since 1982, it has been widely used in the repair and maintenance projects of gezhou dam, dahuofang reservoir, yingxiuwan power station and longyangxia power station. at present, the application of microsilica concrete in ertan power station, zipingpu water conservancy project and xiaolangdi water conservancy project in yellow river has achieved good results.

2. industrial and civil engineering: the microsilica concrete is characterized by early strength and high strength, which is widely used in industrial workshops and high-rise buildings. such as liaoning anshan international hotel c50 concrete, beijing tax building c110 concrete. it can not only increase the strength, reduce the section size, shorten the construction period, but also save the engineering cost.

3. highway construction: make full use of the early strength, high strength and abrasion resistance of the micro-silicon concrete, which can be used to build high-grade highways, airport runways, road tunnel 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, the abrasion resistance increased by 1 time, and the compressive strength reached 37mpa in 24 hours, exceeding the design requirement of c20 concrete. ,

4. port, bridge, and salt water engineering: high density of microsilica  concrete, high resistivity, difficult to form electrochemical damage, and enhanced anti-rust performance. the tsing ma bridge in hong kong, the timber pier in lianyungang, jiangsu province, and the yangtze river bridge in chongqing temple are successful examples.

5. shotcrete engineering: after adding microsilica into the concrete, the adhesive performance and cohesion of the plastic concrete have been significantly improved, the resilient amount has been greatly reduced, the thickness of the first forming of shotcrete has been increased, the construction period has been shortened, and the project cost has been saved. in europe and the united states, 75 percent of shotcrete is mixed with microsilica, while in norway and sweden, microsilica is a necessary ingredient for shotcrete.
