“…Analysing the PZ-EMI response was conducted by cross-correlating, i.e. using a cross-correlation function, the first difference of the impedance signature (dZ) [5] for each sample at age equal to (t), i.e. (dZ(t)), to the first difference of the impedance signature at age equal to (t + 1), i.e.…”

“…Recently, piezoceramics, particularly lead zirconate titanate (PZT), have shown to be effective in monitoring the early strength development of cementitious materials, and they also showed damage detection capabilities when used in civil structures. This makes them considered as multifunctional sensors during the construction and the operational phases [3][4][5]. Through the inverse and the direct piezoelectric effects, see Equation (1), piezoceramics act as actuators and sensors simultaneously when used in the electromechanical impedance mode (EMI) [6].…”

“…Despite the fact that these statistical metrics lack physical meaning and are estimated in a particular frequency range, which makes the frequency range selection crucial to obtain accurate results that match the strength development profile [15][16][17], the strong correlation between the RMSD and compressive strength development has encouraged many researchers to use the RMSD as an indicator of strength development in cementitious materials [10,12,18]. In addition, these statistical indexes showed a frequency-dependent response, which suggestthe changes in the PZT sensing capabilities depend on the used actuation frequency [3][4][5]19,20].…”

“…Visual inspection has long been a common way to achieve this but with the development of the semi-conductor industry the use of structural health monitoring (SHM) techniques has allowed a step change forward towards automation. Traditional SHM is achieved by externally employing measures such as strain gauges, strain sensors, optical fibres, piezoceramic sensors, and so on for the monitoring of strain/stress, cracking, temperature, and corrosion of concrete structures (Fuhr and Huston, 1998;Benmokrane et al, 2007;Gaumet et al, 2021;Ramachandran et al, 2022;Taha et al, 2022). However, these measures are expensive, delicate, not necessarily compatible with concrete structures, and complicated to operate.…”

Carbon fibre incorporated smart cement-based composite has great potential for the multifunctional health monitoring of concrete structures. This paper presents the microstructural, electrical, and mechanical properties of smart cement-based composites incorporating chopped carbon fibres from low dosages at 0–0.1% by volume (vol%) with detailed intervals, to high dosages up to 2.4 vol%. In comparison to a plain mortar, smart cement-based composites at all fibre contents had higher flexural strength. A 95% improvement in flexural strength was obtained at a fibre content of 0.3 vol%, whereas compressive strength increased up to a fibre content of 1.0 vol%, with the highest improvement, 105%, at 0.2 vol%. The bulk conductivity of smart cement-based composites underwent a double percolation process where the percolation zone of the fibres was identified at fibre contents of 0–0.1 vol% and the percolation zone of the capillary pores resided at fibre contents of 2.1–2.4 vol% indicating an extremely low durability. This study presents the laboratory characterization on smart cement-based composites where the fundamentals of the transitional behaviours of the mechanical properties and the percolation in electrical property through fibre loading were studied, which is a necessary step prior to the assessment of the self-sensing performance. The impact of this study will enable the physical properties of carbon fibre incorporated smart cement-based composites to be optimized through the design and manufacturing process. This will lead to robust performance and superior in-situ multi-functional health monitoring of concrete structures.

Damage detection is of great importance for structural construction management and safety. In this study, an ultra-sensitive flexible piezoelectret sensor for damage monitoring in structural health monitoring (SHM) is designed and fabricated, based on excellent electromechanical properties and piezoelectric response characteristics of electret films. The charge stability of the piezoelectret sensor was demonstrated by continuous potential measurement experiments. The experimentally measured piezoelectret coefficient is 6610 pC/N, which is about 10 times that of ordinary piezoelectric ceramics and proves the high sensitivity of piezoelectret. A series of comparative experiments on the piezoelectret sensor and piezoelectric ceramics demonstrate the high performance of the former. According to the damage detection test results, the damage index of cement mortar specimens was obtained. The linear relationship between the damage index and the crack widths proves the excellent performance of the piezoelectret sensor. A piezoelectret array is also used to detect cracks in cement mortar specimens, and can roughly estimate the depth of the fracture based on the damage index (DI) value of the sensing array.
