摘要 | PROBLEM TO BE SOLVED: To provide the corrosion prevention method for a steel, by which the corrosion of the steel such as a reinforcing bar is prevented by surely drying a section up to a section in the vicinity of the steel buried into concrete in a short time. SOLUTION: The surface of concrete 1 is irradiated with microwaves through a horny wave guide 5, which is connected to the surface of concrete 1 and in which a front end is expanded, by using a microwave irradiating machine 3. A space of approximately 10-20 cm is formed between the surface of concrete 1 and the front end of the wave guide 5 while a shielding means such as a wire gauze 7 for preventing the leakage of microwaves is installed around the microwave irradiating machine 3.
