Abstract

L'invention concerne une composition pour béton destinée à la fabrication de blocs moulés en béton de résistance élevée. Elle consiste en 400-600 kg de ciment de Portland par mètre cube de béton, 3-30 % en poids de sulfate de calcium anhydre insoluble de type II, par rapport au poids dudit ciment de Portland et 0,1-3 % en poids d'un agent de dispersion du ciment, par rapport au poids du ciment, l'application de cette composition se faisant à un rapport eau/ciment de 25-35 % en poids, et le pourcentage d'agrégats fins étant de 38-48 %. Grande résistance mécanique, en un jour, par durcissement à la vapeur sous la pression atmosphérique.
