ABSTRACT:
Process and composition 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 blowing agent capable of providing a gaseous component in the strongly alkaline environment either through decomposition or reaction or through vaporization. Inorganic filler material may be added to impart strength, the maximum flexural strength being attained when at least about one-half of the filler comprises microfibers. The resulting cellular product is nonflammable and exhibits essentially zero flame spread, zero smoke density and zero fuel contribution. The cellular products are further characterized as being formed of substantially uniformly sized cells and having densities over a wide range.
