| Abstract(in English) | We proposed a method for evaluation a surface hardness of cement during hardening by measuring a vibration on the surface with high-intensity aerial ultrasonic waves. In this study, we measure the vibration velocity on the material surface under aerial ultrasonic irradiation to evaluate the surface hardness of cement as the surface hardness characteristics change from that of a liquid just after placement to that of a solid. As a result, we demonstrated trend of cement during hardening. Also, we attempted evaluation for suppressing measurements dispersion. |
