“…Benz [2007] proposed a computer model to predict the degree of chloride penetration in concrete with due considerations on electrical conduction, conductivity, and ionic diffusion. Mohamed et al [2014] studied the permeability of chlorides in various types of concrete using salt ponding and rapid chloride permeability methods. Kong and Ge [2015] examined the effect of aggregate size on the permeability of chlorides and found that i) such an effect was noticeable on the porosity of concrete and ii) the aggregate size should be considered when estimating chloride permeability.…”

An experimental program is conducted to study chloride penetration characteristics of concrete partially or fully bonded with carbon fiber reinforced polymer (CFRP) composite sheets in an aggressive service circumstance. A standard test protocol for electrical indication of concrete's ability to resist chloride ion penetration (ASTM C1202) is employed to examine the mobility of chlorides inside the concrete. The ingress of chlorides is influenced by CFRP-coverage ratios such that the current flow and resistivity are reduced with an increasing coverage ratio. The concept of near-field microwave microscopy is exploited to evaluate its potential for scanning CFRP-bonded concrete including chlorides.
