Foamed material
Use of a foamed geopolymer as a fire-resistant sealant material; a method of sealing an aperture or cavity for housing services in a building comprising (i) applying a curable foamed geopolymer composition to the aperture or cavity; and (ii) curing the foamed geopolymer composition, thereby creating a seal in the aperture or cavity and wherein the cured foamed geopolymer has fire-resistant properties; a kit of parts for preparing a foamed geopolymer for use as a fire-resistant sealant material, comprising (i) a container holding a dry mixture of components suitable for preparing a foamed geopolymer including a blowing agent and (ii) a container holding an aqueous alkaline liquid mixture of components suitable for preparing a geopolymer. In a preferred embodiment , the foamed geopolymer is prepared from: (i) 20-30 % by weight of metakaolin, (ii) 20-30 % by weight of muscovite mica, (iii) 35-50 % by weight of aqueous alkali metal silicate solution, (iv) 1-10 % by weight alkali metal hydroxide, and (v) 0.1-5 % by weight of blowing agent.
