The reinforcement and prestressed steel embedded in concrete bridges are corrosing by defferent causes, therefore the steps to protect the steel corrosion in concrete is urgently reguired. In this study, it is devided into several experiment to do study as follow 1) We have examined the deterioration of concrete and the serious corrosion of reinforcement in selected concrete bridges among the concrete bridge under marine environment, and the selected bridge in Young-Dong Highway was tested on field and labarotery to the investigation of corrosion grade and causes. 2)The effect of corrosion protection and the application was verified through the various corrosion protection techigues such as using admixtures, corrosion inhibitor, coated rebor, cathodic protection, surface-coating materials, and the study was accompany for appling reinforced concrete bridges. 3) It was proposed that the design-construction guide for steel corrosion protection of new concrete bridges. For these the case study of advanced nation and data were investigated and to considerate field condition each provision was presented in detail.
