HYDRAULIC COMPOSITION, HIGH-STRENGTH COMPOSITE MATERIAL, AND PROCESS FOR PRODUCING HIGH-STRENGTH COMPOSITE MATERIAL Russian patent published in 1995 - IPC

FIELD: high-strength composite materials. SUBSTANCE: the hydraulic composition comprises 100 wt parts of crushed blast furnace slag, 0.5-5 wt parts of an alkali component selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium methasilicate, 1-15 wt parts of a water-soluble polymer selected from the group consisting of polymethacrylate, polymethacrylamide, methacrylic acid-methacrylamide copolymer, partially hydrolized polyvinyl acetate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, sodium polymethacrylate having a molecular weight greater than 10,000. The composition may further comprise from 2 to 50 wt parts of a fine filler selected from the group consisting of quartz, titanium oxide, calcium carbonate, clay, finely crushed quartz sand, and water. A high-strength composite material is prepared from said composition by a method which comprises mixing said components in the ratio as defined above, molding the mixture and subsequently subjecting the mixture to wet solidification. The resulting material has high banding strength and high water resistance. EFFECT: improved properties of the composite material. 8 cl, 19 tbl
