Outline of Final Research Achievements |
The mechanical characteristics of concrete and mortar were investigated to obtain invisible characteristics of materials using measurement of acoustic emission. It is examined whether a evaluation method of life span could be constructed. As a results, it is inferred that the data of failure types in inner part of materials are obtained from the difference in frequencies of acoustic emission. If it is found the relation between this data and results of simple and easy inspection, it is considered that a method of practical evaluation of life span could be constructed.
