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.
