AbstractA novel cement matrix smart piezoelectric composite and its application as sensing element are presented. A cement matrix smart piezoelectric composite piece encapsulated in a cement mortar formed a practical sensor, and it was tested on material test system with cyclic loading. According to the theoretical analysis, the function of the cement matrix piezoelectric sensor output voltage was expressed in terms of the magnitude of the input cyclic loading amplitude and frequency. The curve fitting of gain function that is defined as sensor's gain factor under different frequencies of input loading was carried out. From the results of curve fitting, it is found that the cement matrix smart piezoelectric composite has a simple relationship between input loading and output voltage. Therefore the cement matrix piezoelectric composite sensor is suitable to be applied in structural health monitoring.
