Galvanic Cathodic Protection (GCP) is one of the most widely adopted electrochemical techniques to prevent further corrosion in concrete structures and extend the service life. Recently, the concrete repair industry is booming and the demand for durable repairs (say, about 25 years) is increasing significantly. Hence, many new galvanic anodes are being introduced in the market; necessitating the assessment of the quality of galvanic anodes and its installations in concrete structures. The prevailing acceptance criteria for evaluating the performance of GCP systems in reinforced concrete relies on the 100-mV polarization shift criterion (EN ISO 12696, 2016). However, this criterion was developed based on corrosion of metals in seawater and soil with low resistivity, which is not suitable for anodes embedded in highly resistive concretes and repair mortars. Consequently, it leads to the disqualification of durable anodes and the qualification of poor-quality anodes. Hence, this research focuses on assessing the suitability of existing acceptance criteria and developing a non-destructive method to evaluate the in-situ performance of GCP systems. A thorough review of relevant literature and knowledge gaps will be presented. Even in projects with lakhs of anode installations, the performance of only about 10 anodes is being inspected. This is due to the lack of needed non-destructive testing techniques. To fill this gap, preliminary studies on electrochemical parameters of steel and zinc in aqueous and cementitious systems were conducted and the results obtained will be presented. Then, the challenges associated with the interpretation of the electrochemical response from a metal concrete system will be presented. Also, how such results will be used for the development of numerical models to represent Concrete-Steel-Anode (C-S-A) systems as an electrical/electrochemical system with steel, concrete, anode, and their interactions will be presented. Objectives and methodology for further experimental and numerical modelling work towards developing non destructive testing techniques for routine inspection (at random locations) of GCP systems and suitable acceptance criteria will also be presented.
