The soft composite silica powder fills the pores of cement particles, forms a gel with hydration products, and forms a gel with alkaline substances. 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, to give you a brief introduction to what the soft composite silicon powder material can play, you can briefly understand. The content is for reference only. Please feel free to contact us for more information.
