Additional information

Calcium silicate is not volatile under environmental conditions due to its chemical nature and inherent physical properties: 

Due to low water solubility and extremely low vapour pressure, calcium silicate is expected to be distributed mainly into soils/sediments, weakly into the water and probably not at all to the air.

It is expected to combine undistinguishably with the soil layer or sediment due to their chemical identity with inorganic soil matter, and it will be subjected to slow natural transformation processes of weathering.
