GEOPOLYMER FOAM FORMULATION FOR A NON-FLAMMABLE SOUND-ABSORBING THERMALLY INSULATING GEOPOLYMER FOAM ELEMENT

摘要

A geopolymer foam formulation comprising: one or more inorganic binders selected from the group consisting of latent hydraulic binders, pozzolan binders, and mixtures thereof; at least one alkaline activator selected from the group consisting of alkali metal hydroxides, alkali metal carbonates, alkali metal aluminates, alkali metal silicates and mixtures thereof; at least one surfactant selected from the group consisting of anionic surfactants, cationic surfactants, non-ionic surfactants and mixtures thereof; gas phase; and water. The formulation may also contain cement and one or more additives for foam stabilization, shrinkage reduction, softening, hydrophobization or dispersion, fibers and fillers or mixtures thereof, and may be single-component or two-component formulations. can Also, methods for the preparation of these formulations through foaming through mechanical introduction of air; the use of this formulation for the manufacture of non-combustible, sound-absorbing, thermally insulating geopolymer foam members; And the geopolymer foam member is proposed.
