“…The porosity increased with increasing FA content. Pan et al 39 investigated pore structures and distribution of PZT-cement composites. The reports show that pores were generally present within the cement matrix, and a few pores were found on the interfacial boundary of PZT particles and cement.…”

Fly ash (FA) is widely used as a supplementary cementitious material in the production of Portland cement concrete. The effect of addition of carbon nanotubes (CNTs) and FA on the properties of barium calcium stannate titanate (BCTS) ceramic-Portland FA cement composites was investigated. These composites have potential for use as sensors and transducers in the monitoring of structural health in concrete structures containing FA. CNTs were found to have filled the pores of the composites. All composites showed good compatibility with the concrete mix. The dielectric constant and electrical conductivity of composites were in the range 200-257 and 1.04 × 10 -6 to 1.66 × 10 −6 S/m, respectively. The presence of FA in composites increased the piezoelectric voltage coefficient (g 33 ). Adding CNTs increased the piezoelectric charge coefficient (d 33 ), thickness electromechanical coupling coefficient (K t ), and also g 33 but decreased mechanical quality factor (Q m ), which is related to good for the receiving sensor and transducer application. CNTs can improve the properties of these composites and composite with FA content at 10 vol.%, and CNTs at 1 vol.% exhibited the highest compressive strength and piezoelectric values (d 33 = 44 pC/N, g 33 = 20.21×10 -3 V m/N, and K t = 18.9%), along with higher g 33 values, than pure BCTS ceramic.

Compatibility, a critical issue between sensing material and host structure, significantly influences the detecting performance (e.g., sensitive, signal-to-noise ratio) of the embedded sensor. To address this issue in concrete-based infrastructural health monitoring, cement-based piezoelectric composites (piezoelectric ceramic particles as a function phase and cementitious materials as a matrix) have attracted continuous attention in the past two decades, dramatically exhibiting superior durability, sensitivity, and compatibility. This review paper performs a synthetical overview of recent advances in theoretical analysis, characterization and simulation, materials selection, the fabrication process, and application of the cement-based piezoelectric composites. The critical issues of each part are also presented. The influencing factors of the materials and fabrication process on the final performance of composites are further discussed. Meanwhile, the application of the composite as a sensing element for various monitoring techniques is summarized. Further study on the experiment and simulation, materials, fabrication technique, and application are also pointed out purposefully.

“…In a smart monitoring system, sensors and actuators are essential components for sensing and controlling purpose. Cement-based piezoelectric composites, by virtue of their excellent piezoelectric properties and good acoustic impedance compatibility with the civil engineering's main structural material-concrete, have been considered to be optimal candidate for smart materials in the eld of civil engineering monitoring [1][2][3][4][5]. In previous research studies, 0-3, 1-3 and 2-2 type (the rst number represents the connectivity of active piezoelectric phase and the second is that of passive cement phase) cement-based piezoelectric composites have been widely investigated [6][7][8][9].…”

In this study, 3-3 type cement-based piezoelectric composites were prepared by casting Portland cement paste in porous lead zirconate titanate (PZT) ceramics, then the Polyvinylidene fluoride (PVDF) of N-Methylpyrrolidone (NMP) solvent with concentration of 50-200 mg/ml was utilized to modify the PZT-PC composites. The influence of PVDF concentration on the density, microstructure, dielectric, piezoelectric and electromechanical properties were investigated. The results indicate that the density of PZT-PC composites increased gradually with PVDF concentration for the increasing combined weight of PVDF with the composites. The introduction of PVDF has also contributed to the reduction of leakage current during the poling and testing process, which led to increased relative permittivity εr and longitudinal piezoelectric strain coefficient d33, while the dielectric loss tanδ and longitudinal piezoelectric voltage coefficient g33 demonstrated an opposite changing trend. Both the thickness electromechanical coupling coefficient Kt and planar electromechanical coupling coefficient Kp of the PZT-PC composites increased with PVDF concentration. The acoustic impedance (Z) of PVDF modified PZT-PC composites ranged from 6.89 to 7.65 MRayls, making it suitable for applications in the health monitoring of civil engineering.
