Analysis of Cement Hydration Monitoring Using Embedded and External Ultrasonic Transducers
This study adopted home-made embedded piezoelectric transducers and external commercial ultrasonic transducers respectively to monitor early hydration processes of cement. This paper discussed the development of ultrasonic amplitude and frequency spectrum during the hydration process. It is proved that the method is effective for monitoring the hydration of cement paste. The embedded transducer could resolve the coupling problem of ultrasonic monitoring and it could be used for the whole life health monitoring of concrete.
