Repair of Highway Bridge damaged by Chloride Attack in Marine Environment(2) - Application of Cathodic Protection

해양에 위치한 고속도로교량에 대한 내염보수 공법(2)-전기방식시공결과

Corrosion of reinforced concrete structures in marine environment is one of the most important mechanism of deterioration. However, conventional rehabilitation techniques in tidal zone, which consist of removing delaminated areas of concrete, cleaning affected steel and patching with portland cements mortar, have proven to be ineffective for marine structures. Also, repairs are often repeated every several years. The purpose of this report is to announce appropriate repair method of highway bridge damaged by chloride attack in marine environment (application of cathodic protection) using FRP and antiwashout underwater mortar.
