The present invention describes improved anhydrite cementitious compositions that control or avoid the problem of undesirable ettringite formation and exhibits similar characteristics to those of Portland cement, as well as procedures for its manufacture. These compositions exhibit good resistance to compression in early stages, good resistance to abrasion and good behavior under water.
L'invention décrit des compositions cimentaires améliorées d'anhydrite qui réduisent ou éliminent le problème de la formation indésirable d'ettringite et qui présentent des caractéristiques similaires à celles du ciment Portland, ainsi que leurs procédés de fabrication. Ces compositions présentent une bonne résistance à la compression dans les stades initiaux, une bonne résistance à l'abrasion et un bon comportement sous l'eau.
