“…Relevant study in reference 27 has shown that chemical reactions occur around the C‐FRCM as the anode of the ICCP system due to the action of current. When an external current passes through the anode (C‐FRCM), an oxidation reaction occurs, wherein electrons are transferred from the anode to react with oxygen (O 2 ) in water, resulting in the production of hydrogen ions (H + ) and water molecules (H 2 O).…”

The dual‐function retrofitting system that uses the carbon‐fabric reinforced cementitious matrix (C‐FRCM) as both the anode of impressed current cathodic protection (ICCP) system and the structural strengthening (SS) material, that is, an ICCP‐SS system, is investigated. The experimental program mainly focused on the shear behavior of C‐FRCM strengthened reinforced concrete (RC) continuous beam under the dual‐function retrofitting system. The influence of anode polarization on the shear strengthening of RC continuous beams is analyzed. Shear tests were conducted on a total of 14 corroded RC continuous beams to investigate the influence of key parameters, including anode polarization degree of prefabricated C‐FRCM plate, layer of carbon fiber mesh and side‐wrapping. The failure modes, shear capacities, and load‐deflection curves of the shear‐strengthened RC continuous beams are reported. Based on the test results, the applicability of relevant design codes was evaluated and found to provide rather conservative predictions for the shear capacity of the examined C‐FRCM strengthened RC continuous beams.

“…In addition, the investigations on advanced anode materials were mainly carried out with isolated anode samples in the reported studies: in most cases, researchers paid more attention to the resistivity reduction in the anode mortar with carbon fibers [ 5 , 23 ], carbon black, or carbon nanotubes [ 24 ]. Despite the conductive enhancing effects and the resulted optimized anode performance discussed, the relationship between the anode mortar and the overall performance was ignored.…”

The local acidification of secondary anode mortar was regarded as the primary reason for the degradation of the anode system, leading to a decreased service life and uneven distribution of the protection current within the impressed current cathodic protection system for reinforced concrete structures. In related previous studies, a novel type of lightweight functional aggregate was designed and prepared for the secondary anode mortar system, aiming to improve anode performance via acidification mitigation. However, the relationship between optimization effects and this functional component has not been fully clarified. In this study, two sets of experiments were carried out to investigate the effects of lightweight functional aggregates on acidification mitigation and the protection of current distribution. Research results proved that the presence of this functional aggregate was beneficial for mitigated acidification propagation and a more uniform distributed protection current, which demonstrated the importance and effectiveness of acidification inhibition on the optimization of anode performance.
