“…There are some outliers due to freezing temperature where the resistance can reach very high values. The resistance of the anodic circuits can vary in the ratio of one to two and are in good agreement with the findings of a previous publication (Ducasse-Lapeyrusse et al, 2023).…”

“…This non homogeneous chloride content may lead to different levels of reinforcement corrosion and corrosion products, which can affect the electrical resistance between the steel and concrete. This hypothesis is supported by the assessment of these zones, as the "Top Outside" zones require a higher current density than other types of zones to meet "criteria b" according to the ISO 12696 standard (AFNOR, 2022), as previously presented in a publication (Ducasse-Lapeyrusse et al, 2023).…”

“…To assess the performance of the ICCP system, the measurement of the potential decay, "criteria b", according to the Standard ISO 12696 (AFNOR, 2022) was used. More information about the ICCP system of the Saint-Cloud Viaduct, the measurement of the potential decay, discussion about the current densities (mA/m² of steel) can be found in a previous publication (Ducasse-Lapeyrusse et al, 2023). This paper focus only on the circuit resistance of the anodic zones constituted by 10 lateral segment webs, on the Saint-Cloud side, i.e., 64 anodic zones (16 "Top Outside", 16 "Top Inside", 16 "Central" and 16 "Bottom" zones) controlled by 16 Control Unit.…”

This paper presents the feedback of the Impressed Current Cathodic Protection (ICCP) system implemented on a road bridge, the Viaduct of Saint-Cloud, constructed in the 1970s in France. After a test trial in 2012, the full-scale ICCP system was energized in 2018. It consisted of 44359 discrete titanium anodes implemented on the lateral segment webs on both sides of the Viaduct, distributed in 212 anodic zones on one side and 153 anodic zones on the other side. The four years monitoring data include the variations of the applied current and tension on anodic zones, their polarization, etc. This paper focus on the global resistance of the circuit for the different anodic zones. The circuit resistance shows first the influence of the temperature. The differences between anodic zones and their evolution over time also bring more information about the environment of the anodes and the reinforcements. The analysis of the response of the circuit reveals the heterogeneity of an actual and large-scale ICCP system and provides important feedback to an appropriate ICCP design for durable cathodic protection.

“…The cathodic protection (CP) systems are another important method to reduce or arrest the corrosion of metal structures by lowering the metal potential using a cathodic current supplied by an anodic system [189,190]. Two main types of CP systems are widely used: sacrificial anode cathodic protection (SACP) and impressed current cathodic protection (ICCP).…”

Applied electrochemistry (AE) plays today an important role in a wide range of fields, including energy conversion and storage, processes, environment, (bio)analytical chemistry, and many others. Electrochemical synthesis is now proven as a promising pathway to avoid all disadvantages in terms of high energy consumption and high pollution, while electrochemical modeling becomes a powerful tool to understand complex systems and predict and optimize the electrochemical devices under various conditions, which reduce study time and cost. The vital role of electrochemistry will greatly be considered in the upcoming years, aiming to reduce carbon footprints and supporting the transition towards a green and more sustainable energy framework. This review article summarizes the recent advances in applied electrochemistry. It shows how this field has become an indispensable tool for innovation, progress, problem-solving in the modern world, and addressing societal challenges across diverse fields.

“…Cathodic protection is an effective way to decrease steel corrosion [19,20]. However, it is difficult to carry out large-scale cathodic protection for steel bars, due to the complexity of the technology construction and operation in concrete structures [21][22][23]. Similarly, the conversion film technique also has limited application for the protection of steel bars in concrete.…”

The corrosion resistance properties of a new type of environmentally-friendly organic inhibitor containing amino ketone molecules are presented in this paper. To evaluate the prevention effect of the inhibitor on corrosion of reinforcement, the electrochemical characteristics of steels in the simulated concrete pore solution (SPS) were investigated under varied conditions of the relevant parameters, including concentrations of the inhibitor and NaCl, pH value, and temperature. The inhibition efficiency of the material was characterized through electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and the weight loss of steels. The results reveal a significant improvement in the corrosion resistance of steels with the inhibitor. A maximum resistance value of 89.07% was achieved at an inhibitor concentration of 4%. Moreover, the new organic inhibitor exhibited good corrosion protection capability for steels under different NaCl concentrations. Its inhibition efficiency was determined to be 65.62, 80.06, and 66.30% at NaCl concentrations of 2, 3.5 and 5%, respectively. On the other hand, it was found that an alkaline environment was favorable for an enhanced corrosion prevention effect, and an optimal pH value of 11.3 was observed in this work. Besides, the inhibition efficiencies at different temperatures showed a trend of 25 > 35 > 40 > 20 > 30 °C, with a maximum value of 81.32% at 25 °C. The above results suggest that the new organic material has high potential to be used as an eco-friendly and long-term durable inhibitor for steel corrosion prevention under complex conditions.
