Abstract
L'invention concerne un procédé pour améliorer la résistance à la compression d'un ciment hydraulique. Un mélange à base d'un ciment hydraulique, d'agrégats et d'une quantité suffisante d'eau pour provoquer la prise hydraulique du ciment est additionné d'un adjuvant constitué par au moins un ester d'acide acétique du glycérol, l'adjuvant étant présent en une quantité suffisante pour accroître la résistance mécanique du mélange à l'état durci. L'adjuvant est de préférence choisi entre la monoacétine, la diacetine, la triacétine et leurs mélanges et il est présent généralement en quantité atteignant 2,0 % en poids sur la base du poids du ciment, habituellement entre 0,01 et 2,0 % en poids. Application à l'amélioration d'un mélange à base d'un ciment Portland ou du type Portland ou d'un ciment à forte teneur en alumine.
