More Information
Summary:A geopolymer foam formulation, comprising at least one inorganic binder comprising metakaolin; 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 alkyl-polyglucoside surfactant; a gas phase and water. This formulation can also comprise a cement, and also additives for foam stabilization, shrinkage reduction, flexibilization, hydrophobization, or dispersion, fibres and fillers or a mixture thereof, and can be a single-component or two-component formulation. An incombustible, sound-absorbing, thermally insulating geopolymer foam element.
