Abstract

Abstract Corrosion is a significant problem in marine environments that ultimately leads to structural failure and economic losses. The assessment of the conditions of concrete piles is an essential part of corrosion prevention measures in marine environments. This research investigated the corrosion potential of concrete marine piles using a half-cell potentiometer. Following this, the observed potential values are subjected to RSM modeling. Approximately ten piles were chosen in Chennai Fishing Harbor, and the corrosion potential values along the depth of the piles in three different zones, namely, the atmospheric, splash and submerged zones, were measured at three-month intervals. Based on the visual inspection, the piles were damaged, and minor cracks developed on the surfaces of the concrete due to the dynamic impact of wave action, specifically in the splash zone. From the results obtained in the field for the chosen piles in the fishing harbor, the corrosion potential values are in the range of −361.45 mV to −527.57 mV in the atmospheric zone, − 520.67 mV to −784.85 mV in the splash zone and– 401.23 mV to—631.28 mV in the submerged zone. RSM was noted to be the most accurate predictor with the highest R2 and least errors. The RSM model captured the variability of the data according to the R2 threshold (R2 > 0.9855). The splash zones have higher corrosion potentials and are more prone to corrosion than the other zones.
