Piezoelectric Impedance Based Elastic Modulus Monitoring for Concrete during Curing
This paper presented an experimental study on piezoelectric impedance based elastic modulus monitoring for concrete during curing. The piezoceramic (PZT) patch was attached on the concrete specimen to collect the monitoring signal. The electro-mechanical impedance (EMI) spectra of surface bonded PZT patch were collected using an impedance analyzer by sweeping the frequency. A regression analysis is conducted to establish the empirical relationship between the relative elastic modulus of concrete and the monitored relative resonant frequency change of the EMI spectra. The established empirical formula is used for concrete elastic modulus monitoring via EMI spectra. The experimental results tell that the EMI technique is a practical and reliable nondestructive test method for concrete elastic modulus monitoring.
