Title:
ORGANIC-INORGANIC COMPOSITE TOUGHENING MATERIAL AND USE THEREOF IN CONCRETE
Document Type and Number:
WIPO Patent Application WO/2024/082735
Kind Code:
A1
Abstract:
An organic-inorganic composite toughening material, comprising a polymerization monomer, a cross-linking agent, an initiator and a micro-interface enhancer, wherein the polymerization monomer is selected from any one or a mixture of acrylamide, an acrylate and a methacrylate; and the micro-interface enhancer is selected from any one or a mixture of nano-wollastonite, calcium carbonate whiskers and calcium sulfate whiskers. When the organic-inorganic composite toughening material is used in concrete, the polymerization monomer is polymerized in situ in the cement concrete under the action of the initiator and the cross-linking agent to form a high-molecular polymer, wherein the polymerization monomer accounts for 1-5% of the mass of the cement. A concrete prepared from the composite toughening material has an improved bending stress resistance and fracture resistance performance without affecting or reducing the compressive strength, thereby improving the problems of low flexural strength, poor toughness, etc., of existing concrete materials.
