| Outline of Final Research Achievements |
This study examined corrosion inhibition effect of temporary coating performed with bridge inspection through accelerated exposure tests and field tests. Because it is difficult to remove completely corrosion of steel substrates surface performed with bridge inspection, the temporary coating is carried out by spray painting without surface preparations of steel substrates. The corrosion inhibition effect of temporary coating is evaluated quantitatively by the variation of thickness of steel specimen before and after the accelerated exposure tests and the measurement of coating thickness of temporary coating in field tests. As the result, it was confirmed that the bridge steel member with temporary coating was more effective of corrosion inhibition than the member without temporary coating.
