| Research Abstract |
The evaluation method of the degree of degradation for agricultural facilities was examined using the elastic wave. Firstly, degraded specimens were prepared by mixing expanded polystyrene (EPS) beads with mortar. The changes in acoustic emission (AE) behavior with increase in strain were measured by Uniaxial compression tests and a splitting tests. Secondly, degraded concrete specimens due to ASR (alkali-silica reaction) were prepared. Accelerations and hit sounds were measured by hammering test. As a result, the knowledge to evaluate qualitatively the degree of degradation using only one sensor was obtained.
