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 membrane.

Hydraulic Cement Concrete Construction Magazine

What is a hydraulic cement and are there chemicals other than calcium chloride that add to the rapid set of concrete? Hydraulic cements are cements which are capable of setting and hardening under water. Lime mortars cannot do this as they need the carbon dioxide of the air to change from the hydrated lime of the mortar to calcium carbonate.
