Abstract

L'invention concerne un procédé de fabrication de produits de béton cellulaire traité à l'autoclave, qui repose sur l'utilisation de mâchefer. Le procédé consiste 1) à sélectionner une quantité adéquate de mâchefer, 2) à transformer le mâchefer en fins granules afin d'augmenter sa surface totale et d'exposer ses composés silicatés, 3) à mélanger le mâchefer transformé à de l'eau pour former une suspension épaisse, 4) à mélanger le béton, de la chaux et de la poudre d'aluminium dans la suspension pour former des cristaux de silicate de calcium, 5) à verser la suspension dans des moules pour former divers composants de construction, 6) à faire durcir dans un premier temps la suspension dans les moules à température et à pression atmosphérique ambiantes, et 7) à faire durcir la suspension dans les moules au moyen de la pression de surface, la température et la vapeur afin de transformer les cristaux de silicate de calcium en Tobermorite.
