PHASE ASSEMBLAGE IN CALCIUM ALUMINATE CEMENTS: A REVIEW

Abstract : Calcium Aluminate Cements (CACs) is used in building chemistry for special applications as self levelling underlayment dry mix mortar for flooring application. Their advantages compared to Portland cement include a high mechanical strength, a rapid setting and drying for rapid hardening repair mortars and a controlled expansion or shrinkage compensation for floor levelers or tile adhesives. Calcium aluminate phases present in different grades of calcium aluminate cements are CaO Al2O3, CaO 2Al2O3 and 12CaO 7Al2O3. The system CaO- Al2O3- H2O has been extensively studied and the aim of this article is an attempt to present a short overview of the phase assemblage in hydrated CACs at ambient temperature and for CACs used in combination with different calcium sulphate sources.
