Calcium+Silicate


 * Calcium silicate** (often referred to by its shortened trade name **Cal-Sil** or **Calsil**) is the chemical compound Ca2SiO4, also known as calcium orthosilicate and sometimes formulated 2CaO.SiO2. It is one of group of compounds obtained by reacting calcium oxide and silica in various ratios [|[3]] e.g. 3CaO.SiO2, [|Ca3SiO5] ; 2CaO.SiO2, Ca2SiO4; 3CaO.2SiO2, Ca3Si2O7 and CaO.SiO2, [|CaSiO3] . Calcium orthosilicate is a white powder with a low bulk density and high physical water absorption. It is used as an anti-caking agent and an antacid. A white free-flowing powder derived from limestone and diatomaceous earth, calcium silicate has no known adverse effects to health[// [|citation needed] //]. It is used in roads, insulation, bricks, roof tiles, table salt [|[4]] and occurs in cements, where it is known asbelite (or in [|cement chemist notation] C2S).
