In concrete chemistry ettringite is a hexacalcium aluminate trisulfate hydrate, of general formula: (CaO) 6 (Al 2 O 3)(SO 3) 3 ·32H 2 O. or (CaO) 3 (Al 2 O 3)(CaSO 4) 3 ·32H 2 O. 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. 2021-03-01 Calcium aluminate cement, also called high alumina cement, has been applied and developed for nearly 100 years.The main composition of calcium aluminate cement is Al2O3, which is in the raw material of bauxite of industrial alumina. calcium aluminate cement are applied widely in various high temperature industries as refractory materials, for monolithic uses. Calcium aluminate concretes supplement traditional ranges of concrete by offering the following properties: very fast hardening: compressive strength in under 3 hours up to 20 MPa controlled wet-edge time: up to a few hours, depending on the mix and admixtures FONDAG®: a dry mix used to obtain very high performance calcium aluminate concrete for the most aggressive environments combining abrasion, erosion, mechanical impact, chemical corrosion, high temperatures & thermal shocks.

The aggregates within Fondag are composed of the same clinker from which calcium aluminate cement is ground. Calcium aluminate cement was originally deve l o p e d for making concrete that is suitable for exposure to sul-fate ground water and sea water. The ground water salts a r e usually calcium sulfate, magnesium sulfate, and sodium sulfate; in sea water, magnesium sulfate is the p r incipal chemical.
