Abstract
A high-strength composite material obtained by kneading a mixture comprising a non-hydraulic inorganic material, a water-soluble polymer and water, molding the kneaded mixture, drying the thus molded material and, optionally, treating the dried molded material with an isocyanate compound, and a process for producing a high-strength composite material which comprises the steps of kneading a mixture comprising a non-hydraulic inorganic material, a water-soluble polymer and water, molding the kneaded mixture, and drying the thus molded material.
Claims4
A composite material having a flexural strength of 244 to 1191 kgf/cm.sup.2 which is obtained by kneading a mixture comprising a non-hydraulic inorganic material selected from the group consisting of blast-furnace slag powder, silica fume, fly ash, silica sand, silica rock powder, calcium carbonate, talc, clay, zeolite, pearlite, diatomaceous earth, kaolin, alumina, titania and zirconia, a water-soluble polymer and water, the water being present in an amount of 5 to 30% by weight based on the non-hydraulic inorganic material, molding the kneaded mixture, and drying the thus molded material.
