Title (EN) PROCESS FOR PREPARING BIOAERATED AUTOCLAVED CEMENT
(FR) PROCÉDÉ DE PRÉPARATION DE CIMENT AUTOCLAVÉ BIOAÉRÉ
Abstract:
(EN) It is described an aqueous mixture or grout containing: a) cementitious material, b) silica sand, c) an aerating agent wherein ii) said aerating agent c) consists of hydrogen peroxide and of a bio-organism containing catalase; iii) said aqueous mixture is obtained without the addition of lime, alkaline and alkaline earth hydroxides and calcium sulphate in hydrated or non-hydrated form. This aqueous mixture is used as starting material in the preparation process of a particular type of autoclaved aerated cement or the autoclaved bioaerated cement here referred to as BAAC.
(FR) 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.
