Introduction to the function of Chengdu silica fume:
1. Significantly improve the compressive, flexural, impermeability, anti-corrosion, impact resistance and wear resistance.
2. It can keep water, prevent segregation and bleeding, and greatly reduce the pumping resistance of concrete.
3. Significantly prolong the service life of concrete. Especially in the harsh environment such as chloride pollution erosion, sulfate erosion and high humidity, the durability of concrete can be doubled or even several times.
4. Greatly reduce the floor ash of sprayed concrete and castable and improve the thickness of single spraying layer.
5. It is a necessary component of high-strength concrete, and C150 concrete has been used in engineering.
6. It has about 5 times the effect of cement. Its application in ordinary concrete and low cement castable can reduce the cost and improve the durability.
7. Effectively prevent concrete alkali aggregate reaction.
8. Improve the compactness of castable refractory. When it coexists with Al2O3, it is easier to form mullite phase, which enhances its high temperature strength and thermal vibration resistance.
9. It has strong pozzolanic effect. When mixing concrete, it can have secondary hydration reaction with cement hydration product Ca (OH) 2 to form cementitious products, fill cement stone structure, improve the microstructure of slurry and improve the mechanical properties and durability of hardened body.
10. Micro silica fume is amorphous spherical particles, which can improve the rheological properties of concrete.
11. The average particle size of micro silica fume is relatively small, which has a good filling effect. It can be filled between cement particles to improve the strength and durability of concrete.
