Introduction to the function of crystalline silicon micro powder

Micro silica powder can fill the pores between cement particles, generate gel with hydration products, and generate gel with alkaline material magnesium oxide. Adding an appropriate amount of microsilica powder to cement-based concrete, mortar, and refractory castables can have the following effects:

1. Significantly improve compressive strength, flexural strength, impermeability, corrosion resistance, impact resistance, and wear resistance.

2. It has the function of retaining water, preventing segregation and bleeding, and significantly reducing the pumping resistance of concrete.

3. Significantly extend the service life of concrete. Especially in harsh environments such as chloride pollution erosion, sulfate erosion, and high humidity, the durability of concrete can be doubled or even multiplied.

4. Significantly reduce the landing ash of sprayed concrete and pouring materials, and increase the thickness of a single spraying layer.

5. It is a necessary component of high-strength concrete and has been applied in engineering with C150 concrete.

6. It has about 5 times the effectiveness of cement and can reduce costs when used in ordinary concrete and low cement castables Improve durability.

7. Effectively prevent the occurrence of concrete alkali aggregate reaction.

8. Improve the density of cast refractory materials. When coexisting with Al2O3, it is easier to generate mullite phase, which enhances its high-temperature strength and thermal vibration resistance.
