Piezoelectric composites based on 0 – 3 cement have been extensively employed in structural health monitoring. Significantly, curing conditions considerably affect the forming strength of matrix materials. In order to obtain the best molding conditions of 0 – 3 cement-based piezoelectric composites, this paper studied the evolution of various parameters with time during the early molding process of 0 – 3 cement-based piezoelectric composites under different temperature and humidity conditions. The analysis indicated that the higher the temperature, which increases the forming speed of the sample, the lower the curing humidity, which decreases the current generated during the polarisation process of the sample, and longer the time required to attain the polarisation voltage. The test concluded that the curing condition of high temperature and high humidity was conducive to obtaining higher piezoelectric and dielectric properties of the sample and the piezoelectric strain constant and dielectric constant reached the maximum value at 80°C/100RH, which were 45.5 pC/N and 44.36 respectively.
