When water is added to cement a chemical process called hydration takes place. Chemicals in the cement chemically react and are transformed into new compounds. [For example, for the combined materials] tetracalcium aluminate + water + calcium hydroxide [corresponds the] transformed compound tetracalcium aluminate hydrate. 4, record 1, English, - dialuminium%20tetracalcium%20heptaoxide%20hydrate
