Abstract

L'invention concerne un mélange aqueux ou un coulis contenant : a) un matériau cimentaire, b) du sable de silice, c) un agent d'aération. Selon l'invention : ii) ledit agent d'aération c) est constitué de peroxyde d'hydrogène et d'un bio-organisme contenant de la catalase ; iii) on obtient ledit mélange aqueux sans ajout de chaux, d'hydroxydes alcalins et alcalino-terreux et de sulfate de calcium sous forme hydratée ou non hydratée. Ce mélange aqueux est utilisé comme matière de départ dans le processus de préparation d'un type particulier de ciment aéré autoclavé ou du ciment bioaéré autoclavé appelé ici baac.The invention relates to an aqueous mixture or a grout containing: a) a cementitious material, b) silica sand, c) an aeration agent. According to the invention: ii) said aeration agent c) consists of hydrogen peroxide and a bio-organism containing catalase; iii) said aqueous mixture is obtained without adding lime, alkali metal and alkaline earth hydroxides and calcium sulphate in hydrated or non-hydrated form. This aqueous mixture is used as a starting material in the process of preparing a particular type of autoclaved aerated cement or autoclaved bio-aerated cement referred to herein as baac.
