Abstract

L'invention concerne un procédé pour fabriquer un béton cellulaire passé à l'autoclave. Un mélange à durcissement rapide est préparé par combinaison d'un matériau contenant de la silice, de chaux vive, d'un agent de rinçage, de gypse, de ciment et d'eau. Ce mélange est déposé dans un moule et y forme un corps durci. Ce corps durci est ôté du moule et placé dans un poste autoclave dans lequel il est étuvé à température et pression élevées. La chaux vive utilisée pour former le mélange à durcissement rapide est modifiée avec un modificateur chimique pour assurer le degré souhaité de réactivité chimique dans le mélange à durcissement rapide.
