“…From these results, it can be seen that all of the samples behave similarly to those in previous studies which show increasing dielectric constant with increasing piezoelectric particle content [1][2][3][4][5][6]. The dielectric constant increases with the increasing BCTZO particle size because of the influence of the dielectric constant of BCTZO bulks (4270 at 1 kHz), which is higher than that of cement bulk (19.7 at 1 kHz) and is explained by the composites model [1,6,12]. It was also found that the dielectric constant decreases with decreasing BCTZO particle size because of the low polarizations in small particles resulting in a lower dielectric constant in the samples.…”

“…This is quite clear from the SEM results. The authors obtained quite good performances compared to those obtained by others at Composites with 70 vol% of piezoelectric particles, the BCTZOcement composites, with average sizes of 569.8 and 8.9 μm have d 33 values of 44 and 52 pC/N, respectively, which are higher than that of the BTO-cement composite (16 pC/N) [6] and the PZT-cement composite (43 pC/N) [3]. Therefore, the authors expect that 1-3 will play a more active role than 0-3 lead free piezoelectric-cement composites for sensors and actuators applications in civil engineering structures.…”

“…In our previous study [11], we investigated the effect of the BT concentration on the dielectric, ferroelectric and piezoelectric properties of 0-3 barium titanate-Portland cement composites. The results of this study indicate that all the properties were improved when the concentration of BT was increased.…”

“…In our previous work [15][16][17][18][19], we investigated the piezoelectric properties of lead-free piezoelectric ceramic-Portland cement composites consisting of lead free piezoelelctric materials, e.g., barium titanate (BT) and barium zirconate titanate (BZT). The results of this work indicate that the acoustic impedance of lead free piezoelectric ceramic-Portland cement composites can be matched with concrete [16][17][18][19].…”
