METHOD FOR STRENGTHENING ADHESIVE PROPERTY OF FRP GRID MATERIAL FOR CONCRETE REINFORCEMENT, FRP GRID MATERIAL FOR CONCRETE REINFORCEMENT AND METHOD FOR REINFORCING CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for strengthening adhesive property of FRP grid material for concrete reinforcement, a FRP grid material for concrete reinforcement and a method for reinforcing concrete structure which increase the adhesive property with the surface of FRP grid material and mortar, etc., suppresses the generation of cracking and minimizes the stripping of a cover of the mortar when being damaged.;SOLUTION: In this method which strengthens the adhesive property with the surrounding concrete 1 and mortar 2 by applying surface treatment to the FRP grid material 100, (1) one primer 3 among a primer (a) prepared by compounding a curing agent into thermosetting resin as base material, a primer (b) prepared by introducing a hydrophilic group into unsaturated polyester resin and vinyl ester resin as base material and compounding a curing agent thereinto and a primer (c) which is polymer emulsion is applied to the surface of the FRP grid material 100 or (2) adhesive resin is applied to the surface of the FRP grid material 100 and adhesive reinforcing material composed of particulate material or fibrous material is adhered thereto.;COPYRIGHT: (C)2003,JPO
