体化が不完全である。■ If the concrete surface is old and the concrete strength is low, even if the adhesive strength of the epoxy resin is high, the adhesive strength (or shear strength) between the concrete and the epoxy resin will be determined by the strength of the weaker concrete on this adhesive surface. Due to this limitation, the integration of concrete and epoxy is incomplete.

ある。■ If there is floating rust, oil film, or skin on the steel material on the surface of the steel material, the adhesion with the epoxy resin will be incomplete and the epoxy resin and steel material will not be completely integrated.
There were many calls for the development of a construction method that would solve the above two problems and completely integrate concrete, epoxy resin, and steel. The present invention has solved this strong demand in a simple and reliable manner.
