A method of making a geopolymer foam is proposed, comprising preparing a foamable formulation, foaming the formulation and curing the foamed formulation. The foamable composition is at least one inorganic binder selected from the group consisting of latent hydraulic binders, pozzolanic binders and mixtures thereof; alkali metal hydroxides, alkali metal carbonates, alkali metal aluminates , At least one alkali stimulator selected from the group consisting of alkali metal silicates and mixtures thereof; at least one surfactant; nanocellulose, and water. The mechanical properties of the foam are improved by incorporating nanocellulose. |
