Crystalline silica micro powder can

Crystalline silica fume can fill the pores between cement particles, form a gel with hydration products, and react with alkaline magnesium oxide to form a gel. In-based concrete, mortar, and refractory castables, adding an appropriate amount of silica fume can achieve the following effects:    Compressive strength, flexural strength, imperme, corrosion resistance, impact resistance, and wear resistance are significantly improved.    It can retain water, prevent segregation and bleeding, and greatly reduce the pumping resistance of concrete. It significantly extends the service life of concrete. Especially in harsh environments such as chloride contamination, sulfate attack, and high humidity, the durability of concrete can be improved by two or even several.
