The crystalline silica powder can fill the pores between cement particles, and at the same time form a gel with the hydration product, and react with the alkaline material magnesium oxide to form a gel. In the cement-based concrete, mortar and refractory castables, mixing an appropriate amount of micro-silica fume can play the following roles:

Crystalline silica powder is made of natural white quartz as raw material, and is refined through multiple processes such as manual selection, high-purity water treatment, fine grinding, filtration, drying, and sieving. Its quality is pure and white. In addition, stable physical and chemical properties and reasonable controllable particle size distribution are widely used in potting materials, encapsulating materials, molding compounds and engineering plastics, silicone rubber, precision ceramics and casting, anticorrosive coatings, Paint and other fields.

Significantly improve the compression resistance, flexural resistance, impermeability, corrosion resistance, impact resistance and wear resistance.

It has the functions of retaining water, preventing segregation, bleeding, and greatly reducing the resistance of concrete pumping.

Significantly prolong the service life of concrete. Especially in harsh environments such as chloride salt pollution erosion, sulfate erosion, and high humidity, the durability of concrete can be doubled or even several times higher.

Significantly reduce the floor ash of sprayed concrete and castables, and increase the thickness of a single spray layer.

It is a necessary component of high-strength concrete, and C150 concrete has been used in engineering.

It has about 5 times the effect of cement, and can reduce costs and improve durability when used in ordinary concrete and low cement castables.

Effectively prevent the occurrence of concrete alkali aggregate reaction.

Improve the compactness of castable refractories. When coexisting with Al2O3, it is easier to form a mullite phase, which increases its high-temperature strength and thermal shock resistance.
