| Outline of Final Research Achievements |
The long durability is expected of a concrete structure. Periodic check and repair are needed to get the long durability. The destructive test from which a pillar core is extracted is best for safety test.The depth and the radius of a reinforcing bar can be confirmed exactly by destructive test. However, it's impossible to check the whole structure, and many costs are also necessary for restoration after a check.
In This research, the method to examine the depth of the reinforcing bar and the diameter of the reinforcing bar is proposed by non-destructive test for which a electromagnetic wave was used.
The method to confirm whether ready mixed concrete satisfies a safety standard is proposed.
