Partial thermodynamic equilibrium and Gibbs energy
The cement fed to the silo contains typically 2% mass of gypsum 2% mass of hemihydrate 96% mass of ground clinker and 50% volume of air. Since the cement is hotter in the center more water vapor is produced there by dehydration. This vapor migrate to the colder side where it eventually produces the reverse reaction: hemihydrate hydration.
