Gypsum can react with calcium aluminate hydrate and form ettringite. As a result, ettringite is pres-ent in the inner parts of concrete where pH remains higher (>4). With the continuing increasing sulfuric acid amount, pH values decrease also in the inner part of the concrete and transform ettringite into gypsum accompanied by volume expansion of the structure.

Calcium Aluminate Cement is a hydraulic binder with normal setting and rapid hardening obtained by finely grinding the resulting product of the combustion mixture of limestone and bauxite. Bauxite is a hydrated aluminum trioxide (Al2O3. NH2O) that contains impurities of silicon dioxide and iron trioxide. Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker. Calcium aluminate cement, also called high alumina cement, has been applied and developed for nearly 100 years.
