Partial thermodynamic equilibrium and Gibbs energy
Apr 22, 2017 · 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.

Keep b ulk gypsum dry until used. Engulfment hazard. To prevent burial or suffocation, do not enter a confined space, such as a silo, bin, bulk truck, or other storage container or vessel that stores or contains gypsum. Gypsum can build up or adhere to the walls of a confined space. The gypsum can release, collapse or fall unexpectedly.

Calcium sulfate - Wikipedia
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in water.

Optimizing cement strength - Cement Lime Gypsum
Storage of cement above 80° C leads to dehydration and release of water reacts with cement and leads to lumps/build ups in silos and also to loss of strength and delayed setting time. Even under ideal storage conditions cement loses its strength value; hence cement should be consumed on the FIFO basis.
