Abstract: TA geopolymer foam having: from 50% to 90% by mass of pozzolanic material polymerized relative to a total mass of the foam; from 0.01% to 2%, by mass of the at least one surfactant relative to the total mass of said foam; and from 1% to 20% by mass of fibers with lengths of between 5 and 1500 ?m relative to the total mass of said foam. A process and a composition for manufacturing the foam, as well applications of the foam, are also disclosed. Finally, the invention relates to a kit comprising said composition for the manufacture of said foam, as well as a pozzolanic material.

Abstract: A process for fireproofing materials, using the following steps: a) placing a material in contact with a viscoelastic suspension obtained by mixing a pozzolanic material with an alkaline activation solution having at least one soluble metal hydroxide; b) geopolymerizing the viscoelastic suspension; c) obtaining a fireproof material with a geopolymer.
