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.
