Semi-encrypted silica fume for shopping centre concrete: This type of microsilica is usually added to the cement used in the construction of shopping centres to increase its fire resistance and corrosion resistance.
Semi-encrypted silica fume is the silica fume after high temperature calcination and semi-enclosed sealing treatment. The chemical composition of semi-encrypted silica fume is very stable, containing a large amount of SiO2, CaO, MgO and other substances, but also has a high degree of activity, and can react with Ca(OH)2 in water to generate new hydration products.
In concrete production, the appropriate addition of semi-encrypted silica fume and fully encrypted silica fume can increase the strength and improve the performance of concrete.
Semi-encrypted silica fume and fully encrypted silica fume can be used in place of part of the cement, which not only improves the strength and durability of concrete, but also reduces the amount of cement used, thus reducing the burden on the environment.
