Piezoelectric properties of 0-3 PZT/sulfoaluminate cement composites

Abstract

A sulfoaluminate cement was, for the first time, used to fabricate 0-3 piezoelectric composites by a compressing technique. The dependences of the piezoelectric properties of composites on the content of PZT and poling conditions are discussed. The results show that the piezoelectric properties of composites are improved by increasing the poling field E and poling time t, but when E and t exceeded 4.0 kV mm−1 and 45 min, d33 tends to be constant. The piezoelectric constants and the electromechanical coupling coefficients Kp, Kt of composites increase rapidly with increasing the content of PZT. When the content of PZT reaches 85%, Kp and Kt are 28.54% and 28.19%, respectively.

Micro-scaled size-dependence of the effective properties of 0–3 PZT–cement composites: Experiments and modeling

“…Lead Zirconate Titanate (PZT) ceramic powders obtained by ball-milling commercial PZT ceramic pieces (Hong Kong Piezo Co. Ltd., Hong Kong, China) and sieved through nylon meshes were used as particles to prepare the 0-3 type cementbased piezoelectric composites. PZT powders were divided into six groups and the average particle sizes are 3,29,43,71,137 and 218 lm, respectively. The particle size distributions were measured by a laser particle size analyzer (LS 230, Coulter Corporation, USA).…”

They have received much research attention in the recent two decades and have appeared to be a prospective novel kind of electromechanical transducer materials in structural health monitoring (SHM) [1,16,17].…”

“…They have received much research attention in the recent two decades and have appeared to be a prospective novel kind of electromechanical transducer materials in structural health monitoring (SHM) [1,16,17]. The overall properties of PZT-cement composites, which are crucial to the transducer performance, generally depend on the physical properties of each constituent, the volume fraction and geometry of PZT particles, as well as the level of electric polarization [2][3][4][5]8,11].…”

Structure–Property Relationships of Nanocomposites

“…It is possible to induce ferroelectric behavior in an inert matrix [Huang et al, 2004] or to improve the piezoand pyroelectricity of polymers. studied the influence of lead magnesium niobate-lead titanate (PMN-PT) particles on the ferroelectric properties of a PVDF-TrFE matrix.…”

Effect of carbon addition on the ferroelectric hysteresis properties of lead zirconate–titanate ceramic–cement composites

“…Cement-based piezoelectric composites consisting of piezoelectric lead zirconate-titanate (Pb(Zr 0.52 Ti 0.48 )O 3 or PZT) ceramic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] play an important role in the development of structural health monitoring of concrete structures, where they can be used as sensors-thus making the structures, so-called, ''smart'' or ''intelligent'' [7]. The use of such composites would provide an advantage in the matching of structural concrete [1].…”
