ABSTRACT OF THE DISCLOSURE Composition and process for forming cellular inorganic plastic cements of magnesium oxychlorides and magnesium oxysulfates. A water slurry containing a magnesium salt, magnesium oxide and a water-soluble phosphate is formed and to it are added an anionic water-repellent surfactant and a liquid fluorinated hydrocarbon blowing agent. Inorganic filler materials are added to impart strength to the cellular product which is nonflammable and exhibits essentially zero flame spread, zero smoke density and zero fuel contribution. The cellular product is formed of substantially uniformly sized cells, a major portion of which are closed and contain residual blowing agent, a fact which makes the cellular product a good thermal insulator. -1-
