| Outline of Final Research Achievements |
In this study, in order to evaluate the quality of cover of reinforced concrete, magnetic impacting method was applied to two types of concrete specimen; one is hardened concrete and another is fresh concrete. As a result, a volume of coarse aggregate in hardened concrete per unit volume could be evaluated by focusing on difference of velocity and frequency spectrum of elastic wave. Furthermore, it was confirmed that elastic wave propagated in fresh concrete can be measured with non-contact sensors.
