Abstract
In the present paper the possibility was studied of the hydration acti vation for high aluminous cements, which have relatively high Al2O3/Ca O molar ratio, with the purpose to maintain good binding properties. C alcium sulphate aluminate (<C(4)A(3)(S)over bar>) was used as an acti vator of the binding properties of these aluminous cements. In this wa y, as a result of a drastic reduction of their calcium oxide content, very good thermomechanical properties of the aluminous concretes can b e obtained.
