<p>PURPOSE:To provide an inorganic composition capable of producing a sufficiently hardened high-quality inorganic molding extremely useful for inner and outer wall materials as an incombustible and smokeless building material by stabilizing reactivity of finely granulated inorganic material comprising silica sand, fly ash, burned bauxite, etc., to increase activity of the inorganic material. CONSTITUTION:An inorganic composition for producing incombustible inorganic molding comprising an aqueous solution of an alkali metal silicate, an inorganic solid component and a filler. Finely granulated inert or active inorganic material the surface of which is coated with an active component composed of alumina sol and/or silica sol is used as the inorganic solid component.</p> |
