| Outline of Final Research Achievements |
In this research, the investigations about influences of concrete pore structure on states of pore solution and its electrical continuity were conducted to clarify the data variance factors of electrochemical measurements on actual structures. Following the progress of the subsequent research, dielectric relaxation measurements were conducted on mortar specimens which contain various materials to ascertain not only pore solution but also charge behaviors in various constituent materials of concrete.
As a result, dielectric relaxation indexes analyzing methods, reproducibility of measurement, pore structure, influences of moisture content or chloride ion on indexes, and quantification method of buried material using electrochemical measurement became clear through the research.
