“…The respective EM observables obtained from these techniques are DC resistivity, as well as low‐ and high‐frequency relative permittivity. These material observables are also dependent on intrinsic material properties and can thus be related to concrete durability indicators (Tumidajski et al ; Villain et al ).…”

“…Firstly, the sensitivity of direct current (DC) electrical resistivity to state parameters linked to environmental conditions (notably water content and chloride content) and concrete porosity is well known (Monfore 1968;Tumidajski et al 1996;Whittington, McCarter, and Forde 1981;Whiting and Nagi 2003). Although DC electrical resistivity formalism is assumed here, it is admitted that low-frequency alternating-current input signals (transmitted current) can be equally used as it was shown that concrete resistivity is not significantly sensitive to input signal frequencies below values of 1000 Hz (Østvik et al 2006), although this fre-Finally, the new device and the inversion protocol enable the determination of a profile of the "true" resistivity over depth equal to about 80 mm (Du Plooy et al 2012).

“…Moreover, when the medium is an element of finite dimensions, a geometric factor must be determined to correct for boundary effects (Marescot et al 2006). This can either be achieved by numerical modelling (Du Plooy et al 2012) or calibration on an electrolyte of known resistivity (Feliu et al 1996).…”

This paper deals with the use of three electromagnetic non‐destructive in situ techniques to assess concrete conditions: electrical resistivity, capacimetry, and ground‐penetrating radar. It shows the potential of these methods to monitor the ingress of water and chlorides into concrete. The electromagnetic properties that are studied here are dielectric permittivity and electrical resistivity, both sensitive to volumetric water content and chloride content. Results are presented from an experimental study conducted on concrete slabs (and corresponding core cylinders) in a controlled laboratory environment. Then, the discussion is focused on the ability of three electromagnetic techniques to assess the depth of the ingress front of different salt solutions and to discern between the 3 NaCl concentrations (0, 15 and 30 g/L).

“…ERT has been studied for many years in geophysical surveys to map the subsurface structure [16][17][18]. In past decades, this method has been successfully applied in medical inspection [19], two-phase flow detection [20] and concrete structure investigation [21]. Recently, the ability of ERT, self-potential method (SP) and distributed temperature sensing (DTS) to monitor, spatially and temporally, temperature changes in the subsurface has been investigated [22].…”

Direct Current (DC) electrical resistivity is a material property that is sensitive to temperature changes. In this paper, the relationship between resistivity and local temperature inside steel shell battery cells (two commercial 10 Ah and 4.5 Ah lithium-ion cells) is innovatively studied by Electrical Resistance Tomography (ERT). The Schlumberger configuration in ERT is applied to divide the cell body into several blocks distributed in different levels, where the apparent resistivities are measured by multi-electrode surface probes. The investigated temperature ranges from −20 to 80 °C . Experimental results have shown that the resistivities mainly depend on temperature changes in each block of the two cells used and the function of the resistivity and temperature can be fitted to the ERT-measurement results in the logistical-plot. Subsequently, the dependence of resistivity on the state of charge (SOC) is investigated, and the SOC range of 70%-100% has a remarkable impact on the resistivity at low temperatures. The proposed approach under a thermal cool down regime is demonstrated to monitor the local transient temperature.
