Analysis of Concrete Beams During the Corrosion Process on Reinforcement Under Tensile Stress

Abstract

This paper aims to the experimental study of reinforced concrete beams subjected to mechanical stresses and simultaneously affected by a corrosion process of their reinforcements. The corrosion process is galvanostatically accelerated applying a certain current density to a limited area of the reinforcements, which are under constant wetting with a solution of Sodium Chloride. The influence of the different degrees of tension in the process of reinforcement corrosion is analyzed through electrochemical monitoring, the cracking advancement in the concrete cover, and the loss of base material in the bars.
