Research Abstract

The objective of this research is to propose a new non destructive prediction system for deterioration of concrete structures in marine environment. From the experimental and analytical examinations, following results were obtained. (1) New simulation models to estimate the progress of chloride induced deterioration were constructed. (2) New monitoring and prediction system for in-service concrete structures in marine environment were established. (3) The critical values of parameters for deterioration prediction were quantitatively determined.
