King Top Industry Group Co.,Ltd

 Microsilica is suitable for high-rise buildings, harbor terminals, reservoir dams, water conservancy, culverts, railways, highways, bridges, subways, tunnels, airport runways, concrete pavement and coal mine roadway anchor spray reinforcement.

Features:

1, Significantly improve the performance of concrete in compression, bending, impermeability, frost resistance, impact and wear resistance;

2, Keep water, prevent segregation and bleeding, drastically reduce the concrete pumping resistance;

3, Significantly increase the density of concrete, extend the service life of concrete, especially in the harsh environment of chloride pollution, erosion, sulfate erosion, high humidity, etc. and can increase durability double or even several times;

4, Improve the cohesiveness of shotcrete, significantly reduce the rebound rate of shotcrete, improve the thickness of single spray layer;

5, Be an important component of high-strength concrete, being applied in C150 concrete project;

6, Has the characteristics of early strength; When micro silica fume is added into the concrete, it will bind with free Ca (OH) 2, thereby reducing the concentration of Ca +2 and OH-, shortening the induction period and promoting the hydration of C2S’

7, Effectively prevent the occurrence of alkali aggregate reaction.
