Reinforced concrete structures are constantly exposed to attacks from external agents, such as chlorides. Therefore, it is important to determine the effectiveness of various protection methods, and among them is hot-dip galvanization. The present research aims to make a comparative analysis of the influence of sodium chloride concentration on the corrosion rate of conventional and galvanized ASTM A615 steel embedded in concrete. To obtain reference values for chloride concentration, soil pits were dug at various points in the Lambayeque department, and groundwater samples were collected and analyzed in the laboratory. Regarding the corrosion assessment, 42 test specimens were fabricated with steel positioned at the center, machined in the center to smooth the lateral face area for more precise corrosion rate measurements. It is also noteworthy that 24 steel specimens underwent a hot-dip galvanization process in a metallurgical company for comparison with conventional steel specimens. After pouring the specimens, they underwent the curing process. During this process, the steel protruding from the concrete was covered with anticorrosive paint to protect it from water splashes from the pits. Finally, the specimens were immersed in different concentrations of sodium chloride, and their corrosion rates were subsequently measured. Varied results were obtained for each case, with a higher corrosion rate in commercial steels, ultimately calculating an effectiveness of over 30% for the zinc coating in the Lambayeque locality.
