“…Experimental study conducted by Wiwattanachang and Giao [11] also investigated the capability of concrete electrical resistivity measurements with Wenner probe method in detecting a crack development in the concrete beams. Artificial cracks made up of plastic sheet inside a concrete beam to simulate insulated cracks as well as cracks being induced in a beam by a four-step loading test on its tension face were studied in this work.…”

Degradation processes in reinforced concrete structures that affect durability are partially controlled by transport of aggressive ions through the concrete microstructure. Ions are charged and the ability of concrete to hold out against transfer of ions greatly relies on its electrical resistivity. Hence, a connection could be expected between electrical resistivity of concrete and the deterioration processes such as increase in permeability and corrosion of embedded steel. Through this paper, an extensive literature review has been done to address relationship between concrete electrical resistivity and its certain durability characteristics. These durability characteristics include chloride diffusivity and corrosion of reinforcement as these have major influence on concrete degradation process. Overall, there exists an inverse or direct proportional correlation between these parameters. Evaluated results, from measuring the concrete electrical resistivity, can also be used as a great indicator to identify early age characteristics of fresh concrete and for evaluation of its properties, determination of moisture content, connectivity of the micropores, and even condition assessment of in-service structures. This paper also reviews and assesses research concerning the influential parameters such as environmental conditions and presence of steel rebar and cracks on measuring electrical resistivity of concrete. Moreover, concrete resistivity concept, application, and its various measurement techniques are introduced.

“…ERT processing Accurate geometric factors were generated through a 3D numerical model of the levee (using the COMSOL Multiphysics® finite element environment) to avoid misinterpretation from 3D effect artifacts (Rücker et al 2006;Lin et al, 2014). In the levee model, the embankment topography, the actual positions of both lines of embedded electrodes and the actual height of the Loire river at the time of each ERT acquisition are considered (Marescot et al, 2006;Wiwattanachang and Giao, 2011;Jodry et al, 2017). The observed apparent resistivity datasets were inverted using RES2Dinv commercial software (version 3.59) (Loke and Barker, 1996).…”

We present a study of the seasonal behaviour of soil moisture in an old embankment levee by means of 2D DC-electrical resistivity tomography monitoring based on an embedded electrode installation. We were able to produce seasonal resistivity change models that are compensated for temperature effects using a seasonal temperature profile model. Time-lapse sections of percentage resistivity changes show spatial and temporal overall consistency with seasonal variations of soil temperature. Discrepancies are likely due to the pavement layer that is not well considered in the inversion process as well as to time-lapse inversion pitfalls. Furthermore, a detailed estimation of seasonal moisture content variations could not be given as an accurate calibration of the employed suction probes was not achievable. Nevertheless, the levee appears to have spatially consistent time variations in soil moisture, clearly influenced by both rainfall and water table and river levels. Future work on developing 3D acquisitions and adding embedded moisture content probes should prove effective to our monitoring design and give a more detailed understanding of the soil moisture seasonal behaviour in the studied stretch of levee.

“…Since its original use by Shimizu in the 1920's (Shimizu, 1928), many researchers have sought to use electrical measurements to describe hydration (Curran & McCarter, 1984;Osterminski, Polder, & Schießl, 2012;Sohn & Mason, 1998;Van Beek & Hilhorst, 1999;Wei & Xiao, 2014), transport properties (Ramezanianpour, Pilvar, Mahdikhani, & Moodi, 2011;Tang, Nilsson, & Basheer, 2011), or cracking (Chung, 2003;Niemuth, 2004;Peled, Torrents, Mason, Shah, & Garboczi, 2001;Pour-Ghaz, Niemuth, & Weiss, 2013;Taillet, Lataste, Rivard, & Denis, 2014;Wiwattanachang & Giao, 2011). Electrical testing has many advantages due to the low cost of testing equipment and short time duration that is needed to perform the test.…”

The Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction, operation, management and economic efficiency of the Indiana transportation infrastructure. https://engineering.purdue.edu/JTRP/index_html AbstractINDOT (as well as several surrounding states) have observed that certain concrete pavements may show a susceptibility to joint deterioration. Unfortunately, by the time that this joint deterioration is observed it is often too late and costly partial depth repairs are needed. The deterioration is generally occurring in the joint behind the backer rod and joint sealant; as such, it is difficult to detect even if one is standing directly above the joint. This project investigated the use of electrical resistivity and ground penetrating radar as two techniques to detect premature joint deterioration. The thought process was that if the joint deterioration is determined at an early stage, low cost corrective actions can be taken to extend the life of the concrete. The electrical response was measured for mortars subjected to a temperature cycle from 23 °C to -35 °C, with varying degrees of saturation, and varying salt concentrations. The resistivity increased as the degree of saturation was reduced due to the reduction in the volume of the conductive medium and increase in tortuosity. Changes in resistivity were detected when cracking occurred in the sample. The magnitude of these changes was similar to that detected using changes in the ultrasonic wave speed. Ground penetrating radar (GPR) was used effectively to detect fluid accumulation in the saw-cut joint behind the joint sealant. The typical GPR waveforms are however difficult and time consuming to interpret. A signal processing approach called, referred to as the CID, was used to obtain a single number that reflects the potential for fluid in the joint. Scalar waveform features and the computed CID can be used to estimate which joints may contain fluid thereby providing insights into which joint sealant sections may need to be repaired or when a sufficient number of joints may contain fluid suggesting a larger joint maintenance effort be performed to seal the joints or the concrete.17.
