900microsilica【价格 厂家 供应】-pg电玩城

900microsilica:the appearance is gray powder, sio2 content is 85-87%, and there are encryption and semi-encryption products, which can be applied to large concrete projects, mortar, ground floor, pipe piles, etc., as necessary admixture.

900microsilica is able to fill the pores between cement particles, and at the same time form gels with hydration products, and form gels by reacting with magnesium oxide, an alkaline material. in the cement based concrete and mortar, the addition of appropriate amount of silica fume can play the following role:

1. significantly improve the anti-pressure, anti-folding, anti-permeability, anti-corrosion, anti-impact and anti-wear properties

2. it can protect water, prevent segregation, bleed water and greatly reduce concrete pumping resistance

3. significantly extend the service life of concrete. especially under the harsh environment of chlorine salt pollution erosion, sulfate erosion and high humidity, the durability of concrete can be doubled or even multiplied

4. substantially reduce the landing dust of sprayed concrete and castable, and increase the thickness of single spraying layer

5. as a necessary component of high-strength concrete, c150 concrete has been applied in engineering

6. it has the effect of about 5 times of cement (application in ordinary concrete and low-cement castable can reduce cost and improve durability)

7. effectively prevent the occurrence of concrete alkali aggregate reaction
