法は、ごく限られた部分にしか実施されていない。(Prior Art) Concrete Reinforcement Material 9 For example, reinforcing bars undergo corrosion and volumetric expansion due to rainwater and/or moisture infiltrated through cracks in the concrete, alkali of the concrete itself, and the like. The volumetric expansion of the reinforcing bars further causes cracks in the concrete, shortening the service life of concrete structures. For this purpose, coatings with various resins have been used, but they are not sufficiently effective in preventing corrosion of reinforcing bars due to insufficient alkali resistance and water resistance. Therefore, this conventional method has only been implemented in a limited number of areas.
