<p>PROBLEM TO BE SOLVED: To provide: an injection material injecting method for a concrete structure in which a head of epoxy resin is prevented from swelling and jumping out from a surface of a concrete wall surface or floor surface in summer, even when the epoxy resin as an injection material is injected from a hole drilled by a drill in a concrete structure and is cured; and an injection material used therefor.SOLUTION: In an injection material injecting method for a concrete structure: when epoxy resin is injected into a cavity such as a crack of a concrete structure, a hole is drilled in the concrete structure and the epoxy resin as an injection material is injected from the drilled hole into a crack, a rock pocket, or a cavity around a reinforcement and is cured; and the drilled hole is filled with the epoxy resin to be cured. The epoxy resin which is the injection material for the method is composed of a liquid bisphenol type diglycidyl ether, a styrene additional meta xylene diamine, an alicyclic amine, and a mercaptan terminal polysulfide chemical compound.</p> |
