How much is the content of silica in cement?
The main ingredients of cement are calcium silicate two, silicic acid three calcium, and aluminium acid three calcium, respectively2CaO *SiO2,3CaO*SiO2,3CaO*Al2O3Come on, SiO2%=17.9%Not counting impurities,
There are two kinds of crystalline silica and amorphous silica in nature. Silica is widely used, mainly used in making glass, water glass, pottery, ceramic, refractory material, aerogel blanket, ferrosilicon, silicon sand, cement, etc., in ancient times, silica is used to make the glaze porcelain and carcass. Ordinary stones consist mainly of silica and calcium carbonate.
Silica, chemistry, pure silica is colorless, is solid at normal temperature, chemical formula SiO, insoluble in water. Insoluble in acids but soluble in hydrofluoric acid and hot concentrated phosphoric acid, used in combination with molten bases.
