EVALUATION ON PARAMETERS OF CHLORIDE INDUCED DAMAGE BASED ON ACTUAL DATA IN SITU

Abstract

Since chloride induced deterioration of structures are mainly governed by the local atmosphere where target structures are located, the parameters need to be obtained by using actual data in situ.
The data of deterioration obtained from existing concrete structures of thermal power plants over 20 years along Tokyo Bay are analyzed and studied in this paper.
Then, the parameters such as chloride ion density, diffusion coefficient and corrosion speed of reinforcement to chloride induced damage are investigated.
