Calcium silicate, we also call it Ca-Si or CaSi, is the chemical compound Ca2SiO4, also known as calcium orthosilicate and sometimes formulated by 2CaO.SiO2. It is one of a group of compounds obtained by reacting calcium oxide and silica in various ratios, e.g. 3CaO•SiO2, Ca3SiO5; 2CaO•SiO2, Ca2SiO4; 3CaO•2SiO2, Ca3Si2O7 and CaO•SiO2, CaSiO3. Calcium silicate is […]
