Silica powder fills the pores between cement particles to form a hydrated product gel, which contains alkaline substance mgo gel. In cement-based concrete, mortar and refractory materials, mixing silica fume in an appropriate amount can significantly improve the concrete's compressive, flexural, impermeable, corrosion-resistant, impact-resistant and wear-resistant properties. The utility model has the functions of retaining water, preventing segregation, bleeding, and greatly reducing concrete pumping resistance. Greatly extend the service life of concrete.

It can greatly reduce the ground ash content of shotcrete and castables, and increase the thickness of a single shotcrete layer. It is an important part of high-strength concrete and has been applied in c150 concrete engineering. Used in ordinary concrete and low cement castables, the cement effect is about 5 times that of ordinary concrete and low cement castables, reducing costs. Improve durability. Effectively prevent concrete alkali aggregate reaction. Improve the compactness of cast refractories.

When Al2o3 coexists with mullite, it is easy to form a mullite phase, which makes mullite have higher temperature strength and better thermal shock resistance.

The above is a small series telling you that silica powder can effectively prevent concrete alkali-aggregate reaction. You can take a look at it briefly. The content is for your reference only, you can contact our manufacturer if you want to know about it.
