Calcium silicate - Wikipedia

Calcium silicate is a white free-flowing powder. It can be derived from naturally occurring limestone and diatomaceous earth, a siliceous sedimentary rock. It is one of a group of compounds that can be produced by reacting calcium oxide and silica in various ratios e.g. 3CaO·SiO2, Ca3SiO5; 2CaO·SiO2, Ca2SiO4; 3CaO·2SiO2, Ca3Si2O7 and CaO·SiO2, CaSiO3. It has a low bulk density and high physical water absorption.
