Disclosed is a process for preparing a solid, light weight mineral foam which is stable during its preparation and during its subsequent curing and drying and which, thanks to its composition and the way it is prepared, can be injected in situ, substantially like a urethane foam. This foam has a density ranging from 10 to 65 lb/pi 3 and is made of 1 part by weight of a solution of phosphoric acid of given concentration in which is dissolved polyvinyl alcohol in such an amount as to make the solution viscous; from 0.03 to 6 parts by weight of wollastonite containing from 0.5 to 4% by weight of a carbonate salt; and from 0.2 to 10 parts by weight of water. The amount of water depends on the concentration of the solution of phosphoric acid and of the required density of the foam, it being understood that the more concentrated is the solution of phosphoric acid and/or the lower is the required density, the higher is the amount of water. The products made of such a foam are rigid and can be used for thermal and acoustic insulation.
