PURPOSE:To preven the corrosion of a steel material in the part to be attached to concrete by covering the steel material to be embedded into the concrete from its exposed part up to the embedded part with petrolatum tapes or sheets for corrosion prevention. CONSTITUTION:Paint 3 for corrosion prevention is painted on a steel material 1 from its exposed part up to embedded part bodering at the surface 2a of concrete 2, and coverings of petrolatum tapes 4 for corrosion prevention are applied thereon. In the stage of application, the material 1 is beforehand painted with the paint 3 and covered with the tapes 4 prior to placing of concrete. There is a sufficient effect even without application of said paint 3. By the above-mentioned method, the material 1 is covered with the tapes 4 having high adhesiveness, the influence of water and air that are the cause for corrosion and the entry of corrosive materials are prevented, and further electrolytic corrosion is prevented by the tapes 4 having high insulation characterustic, whereby a high corrosion preventive effect is obtained. |
