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 material casting, mixing with a proper amount of micro-silica fume can achieve the following effects:

Significantly improve compressive, flexural, impermeable, anti-corrosion, impact and wear resistance.

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

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

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

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

It has about 5 times the effect of cement. It can reduce costs and improve durability when used in general concrete and low-cement casting.

Effectively avoid the occurrence of concrete alkali aggregate reaction.

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