THE SURFACE REPAIR METHOD OF CONCRETE STRUCTURE

摘要

A method for repairing the surface of a concrete structure is provided to prevent the concrete structure from being degraded and deteriorated, and to prevent damage from sea wind, by improving adhesive force of the concrete structure and a repaired part and preventing separation of the concrete structure and a repaired part. A method for repairing the surface of a concrete structure comprises a step of flattening and cleaning the surface of the concrete structure needing repair(S1); a step of spreading and curing of a primer of very low viscosity on the concrete structure many times(S2); a step of attaching a staple fiber to the semi-cured primer layer by blowing compressed air(S3); a step of spreading impregnation resin of very low viscosity on the flocked surface of the staple fiber(S4); a step of attaching a fixing mesh(S5); a step of spreading impregnation resin and smoothing the surface(S6); and a step of forming a film layer by spreading a urethane paint on the surface where the impregnation resin is hardened and sufficiently drying the film layer(S7).
