Ettringite - Wikipedia

Ettringite is formed in hydrated Portland cement system as a result of the reaction of calcium aluminate with calcium sulfate, both present in Portland cement. Ettringite, the more prominent representative of AFt phases or (Al 2 O 3 -Fe 2 O 3 -tri), can also be synthesized in the laboratory by reacting stoichiometric amounts of calcium , aluminium and sulfate in water.
