Abstract

This work presents the electrochemical evaluation of bars of Galvanized Steel and AISI 1018 with 3/8” and ½” of diameter, this bars are commonly used for the construction of elements based on Soils Mechanically Reinforced (SMR), the bars were buried in a fine soil predominant in the region of Xalapa City, Ver., México, soil classified in the USCS (Unified Soil Classification System) as a high plasticity silt (MH). Corrosion evaluation was conducted by monitoring the corrosion potential Ecorr and corrosion rate, Icorr, using techniques half-cell potential according to the standard ASTM C-876-15 and Linear Polarization Resistance (LPR), respectively. The experimental setup simulates the real conditions when the steel is used as reinforcement in structures of SMR, where they remain buried throughout the useful life of the structure. The results of the first 110 days of exposure show that the Galvanized Steel bars have a better corrosion performance compared to the AISI 1018 steel regardless of their diameter.
