“…A similar range of resistivities, between 45 and 379 O.m, is reported by Andrade et al [56], for NWC with w/b ratios of 0.28 and 0.56 produced with cement type I 42.5R and different amounts of SF, natural pozzolans and FA.…”

“…This is explained by the progressive hydration due to the production of higher amounts of the smaller (gel) pores. Thus, the pore space for the access of the external chloride is reduced (Andrade et al, 2011(Andrade et al, , 2013(Andrade et al, , 2014.…”

“…Additionally, to account for the retardation of chloride penetration due to the chloride reaction or binding with the cement phases, a factor needs to be applied to electrical resistivity measurements [59]. A reaction factor ( cl ) is defined as the ratio between the diffusion coefficients app and eff assuming lineal chloride binding as shown in (14) where app and eff are apparent and effective electrical resistivity [59]:…”

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.
