1 It can significantly improve the properties of compression resistance, folding resistance, impermeability, corrosion resistance, impact resistance and wear resistance

2 It has the function of retaining water, preventing segregation and bleeding water and greatly reducing the pump resistance of concrete

3 The service life of concrete can be extended remarkably, especially in the harsh environment of chloride pollution, sulfate erosion and high humidity, which can increase the durability of concrete by one or even several times. 

4 Greatly reduce the jet concrete and castable ash, improve the thickness of a single spray layer.

5 It is a necessary component of high strength concrete .

6 It has about 5 times the effect of cement and can reduce the cost and improve the durability when it is used in ordinary concrete and low cement castable.

7 Effectively prevent the concrete alkali aggregate reaction.

8 Improve the density of castable refractories. When coexisting with Al2O3, it is easier to generate mullite phase, so as to enhance its high-temperature strength and thermal vibration resistance
