High Quality Silica Fume / Microsilica with low price

Silica ash can fill the pores between cement particles, at the same time with hydration products to produce gel, and alkaline material magnesium oxide reaction to produce gel.

In cement-based concrete, mortar and refractory castable, the appropriate amount of silica ash can play the following role:

1, significantly improve the pressure resistance, anti-folding, anti-seepage, anti-corrosion, impact resistance and wear resistance.

2, with water retention, prevention of segregation, drainage, greatly reduce the role of concrete pump resistance. 3, significantly extend the service life of concrete.

Especially in the harsh environment such as chlorine salt pollution erosion, sulfate erosion and high humidity, the durability of concrete can be increased one or even several times.

4, greatly reduce the injection of concrete and pouring material floor ash, improve the thickness of a single spray layer.

5, is a necessary component of high-strength concrete, has C150 concrete engineering applications.

6, with about 5 times times the effect of cement, in ordinary concrete and low cement castable application can reduce costs. Improve durability.

7, effectively prevent the occurrence of concrete alkali aggregate reaction. 8, improve the density of pouring refractories. 
When coexisting with Al2O3, it is easier to generate mullite facies, so that its high temperature strength, anti-thermal vibration enhancement.
