- Synopsis:
- Recently, the mass media pays attention to few cases of deterioration and damages on concrete structures. In order to prevent the deterioration and damages, it is necessary to improve the quality control. The anti-corrosion coating has been applied to some concrete structures as countermeasures against the deterioration since 1983 in NIHON DORO KODAN (Japan Highway Pubic Corporation: JH). However, the coating seldom satisfied the requirement in terms of the durability and elongation, depending on the conditions. Therefore, JH have hesitated to apply the coating to the concrete structures all over Japan. This paper describes a proposed evaluation method concerning durability and adhesion capability including the basic parameters, based on a follow-up survey on anti-corrosion concrete surface coating applied on piers of the URADO Bridge.
