摘要: Piezoelectric properties of 0–3 type cement-based piezoelectric composites with fly ash are investigated, where the inclusion is PZT, and binder consists cement ash. Cement was replaced by from 10 % to 50 vol.% in binder. Experimental results indicate that all ash/cement can be successfully polarized. Prior polarization, relative dielectric constant er increases ash, but diminishes curing time. stable at 50th day after polarization. Curing time not sensitive properties, polarizing voltage is. A 20 replacement composite PZT reaches a maximum value 54 pC/N 28 × 10−3 V-m/N for d33 g33, respectively.
