Abstract
A geopolymer foam formulation, comprising at least one inorganic binder selected from the group consisting of latently hydraulic binders, pozzolanic 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; a gas phase and water. This formulation can also comprise a cement, and also additives for foam stabilization, shrinkage reduction, flexibilization, hydrophobization, or dispersion, fibers and fillers or a mixture thereof, and can be a single-component or two-component formulation. Also, a process for the production of this formulation via foaming by mechanical introduction of air, the use of the formulation for the production of an incombustible, sound-absorbing, thermally insulating geopolymer foam element and the geopolymer foam element.
