“…However, proposed model in Chouteau and Beaulieu [77] only identified the effect on resistivity measurements as being different when cracking was present. In addition, to evaluate and detect cracks and discontinuities, such as joints, in massive concrete structures within preexisting boreholes, electrical resistivity measurements with a DC current was stated to be a good quality assessment indicator [78]; however, using a DC current rather than AC current may result in unfavorable results due to polarization effect which was not considered in Taillet et al [78].…”

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.

“…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.

“…The rapid chloride permeability test, which is based on electrical conductivity, is widely applied in the estimation of the durability of CBMs (Aashto, 2015;ASTM, 2010;Xiao et al, 2016). Electrical properties are also frequently considered as effective ways of studying the early-age properties of CBMs (Dong et al, 2016;Xiao and Li, 2008) and detecting cracks in CBMs (Lataste et al, 2003;Taillet et al, 2014).…”

Electrical conductivity is one of the most important indicators of the durability, impermeability and frost resistance of cement-based materials (CBMs). It is also a main performance parameter for some special CBMs such as insulating concrete and electrically conductive concrete. The aim of this study was to examine the relationship between electrical conductivity and saturation degree of CBMs more deeply by considering the pore size distribution (PSD), which is described in a new way. The distribution of the pore solution (the main conducting medium) in CBMs was analysed by considering the PSD function, the Kelvin equation and theories of capillary and surface adsorption. According to the pore solution distribution and conductivity theory, a conducting tube network model was established. The curves obtained by the proposed model were found to fit the experimental data well. The conducting tube network model was then used to analyse the factors influencing the electrical conductivity of CBMs. The conclusions obtained from this study were that the electrical conductivity of CBMs varies with the relative ratio of large and small pores and the mean value and standard deviation of large pores, and that the electrical conductivity of CBMs is proportional to the pore solution conductivity and porosity of the CBM.
