Calcium Aluminate Cement Concrete| Concrete Construction

Calcium aluminate cement concretes are not rapid setting. They are, however, rapid hardening; that is, they will develop as much strength in 24 hours as Portland cement concrete will achieve in 28 days. Calcium aluminate cement concretes should be cured for at least 24 hours, using a water spray or fog, ponding, wet burlap or a curing merane.

Structure-property relations in calcium aluminate glasses

Calcium aluminate glasses are transparent in the infrared region, exhibit ultralow optical losses, and possess excellent mechanical properties. However, these systems exhibit poor glass-forming ability, and it is therefore important to understand their composition-structure-property relations to enable the design of new compositions with optimized properties and glass-forming ability.

Kinetics, shrinkage, microstructures and material

In PC-dominated formulations a temporary inhibition of tri-calcium aluminate (C 3 A) seems to reduce the reaction intensity. Thus, gypsum is formed as an intermediate hydrate. Later this gypsum is consumed to produce further ettringite. The large reservoir of tri-calcium silie (C 3 S) causes hydration to last as long as water is available
