Resumen:
Reinforced concrete is a reliable building material due to many excellent properties such as strength and durability. However, marine environments and chloride-contaminated aggregates accelerate deterioration and failure[1]. Inorganic inhibitors are frequently considered to mitigate steel corrosion [2,3]. In this work, silicate ions were tested as corrosion inhibitors in concrete pore simulating solutions contaminated with chloride ions. The electrochemical evaluation included cyclic voltammetry and polarization curves. Weight loss tests were implemented to follow the inhibitor performance over long exposure times. Micro-Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) were used to investigate the composition of the surface film.
