REPAIRING AND REINFORCING MATERIAL FOR CONCRETE STRUCTURE AND METHOD OF REPAIRING AND REINFORCING CONCRETE STRUCTURE USING THE SAME

摘要

The present invention relates to a material for repairing and reinforcing a concrete structure and a construction method for repairing and reinforcing a concrete structure using the same. According to the present invention, an acryl-based mixed resin is used for repairing and reinforcing a damaged concrete structure, in particular, second powder components including oystershells powder, waste glass powder, etc. are used, thus physical properties such as bending strength, tensile strength, compressive strength, etc. are excellent, furthermore, adhesion performance with the concrete structure, chemical resistance, waterproof properties, resistance to salt damage, and shielding performance for radioactivity are excellent due to first powder components including clinker, cast, plaster, and etc. Also, since resin components and initiator components are separated from one another, and powder components are used by being divided into the first and second powder components, and separate cellulosic long fiber components are also added, thus storage stability is excellent due to non-curable properties even for a long-term storage, and since each component are used by being mixed right before use, a service period is not limited, use in the field is convenient, and material loss and environmental contamination caused by residual materials, are prevented.
