Abstract
A cellular product useful for such purposes as fireproofing, thermal insulation, and acoustical soundproofing, may be produced from a mineral cement, such as portland cement, calcium aluminate cement, and gypsum cement, a water soluble organic film-former, an emulsion of a synthetic resin with a glass transition temperature of 10.degree.-25.degree. C, a mixture of anionic and nonionic surfactants, an aggregate, and air in an amount substantially in excess of that used in air entrainment of cements, admixed in the form of a stabilized foam, whereby the product has a density which is substantially lower than the density of the mineral cement and aggregate per se.
