  • Advanced geopolymer composites
    Patent number: 5244726
    Abstract: A self-hardened, high temperature-resistant, foamed composite is described. An alkali metal silicate-based matrix devoid of chemical water has dispersed therein inorganic particulates, organic particulates, or a mixture of inorganic and organic particulates, and is produced at ambient temperature by activating the silicates of an aqueous, air-entrained gel containing matrix-forming silicate, particulates, flyash, surfactant, and a pH-lowering and buffering agent.
    Type: Grant
    Filed: August 31, 1992
    Date of Patent: September 14, 1993
    Assignee: The HERA Corporation
    Inventors: Bill E. Laney, F. Truman Williams, Ronald L. Rutherford, David T. Bailey
  • Geopolymer-modified, gypsum-based construction materials
    Patent number: 5194091
    Abstract: Geopolymer-modified gypsum construction materials. Compositions derived from combining geopolymer adhesives with conventional gypsum wallboard slurry formulations produce an interpenetrating network (IPN) which cures by loss of process water to a refractory solid having improved fire and water resistance. Geopolymer adhesive starting compositions includes soluble and insoluble silicates, buffers and salts, and a chemical setting agent in aqueous suspension.
