Abstract: 0-3 cement-based piezoelectric composites were fabricated using sulphoaluminate cement and piezoelectric ceramic [0.08 Pb(Li1/4Nb3/4)O•0.47PbTiO3•0.45PbZrO3] as raw materials by compressing technique. The influences of carbon black content on the piezoelectric and dielectric properties, electric conductivity and impedance were investigated. The results indicate that the piezoelectric strain constant d33 and piezoelectric voltage constant g33 of the composites increase gradually with a suitable carbon black addition. When the carbon black content is 0.3wt%, both of the piezoelectric strain constant d33 and piezoelectric voltage constant g33 of the composite exist the maximum value, which are 17.45 pC.N-1 and 36.3 mV·m.N-1, respectively. As the carbon black content increases, the dielectric constant, dielectric loss, electric conductivity of the composites all increase, while the impedance decreases.
