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.
