Calcium silicate (often referred to by its shortened trade name Cal-Sil or Calsil) is the chemical compound CaSiO, also known as calcium orthosilicate and sometimes formulated 2CaO.SiO. It is one of a group of compounds obtained by reacting calcium oxide and silica in various ratios e.g. 3CaO•SiO, CaSiO; 2CaO•SiO, CaSiO; 3CaO•2SiO, CaSiO and CaO•SiO, CaSiO. Calcium silicate is a white free-flowing powder derived from limestone and diatomaceous earth. It has a low bulk density and high physical water absorption. It is used in roads, insulation, bricks, roof tiles, table salt and occurs in cements, where it is known as belite (or in cement chemist notation CS).
It is used as an anti-caking agent in food preparation and an antacid. It is approved by the United Nations' FAO and WHO bodies as a safe food additive in a large variety of products.
