| Outline of Final Research Achievements |
In order to construct a prediction method of chloride ion permeation for unsaturated concrete based on the electrical properties of concrete obtained by some electrochemical nondestructive tests, this study stacked and summarized the basic knowledge - namely, (1) the relationship between apparent diffusion coefficient and electric resistance of unsaturated cement paste, (2) the relationship between apparent diffusion coefficient of chloride ion of concrete immersed in seawater for a long time and diffusion coefficient estimated from electric resistivity, (3) the development of nondestructive evaluation test of moisture content distribution in concrete.
