calcium aluminate cement alumina cement aluminous cement
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
