Abstract: [EN] This work presents the three-year results of the project: Effect of the environment on reinforcement durability (DURACON), which is investigating the influence of the meteorochemical parameters of marine and coastal-marine environments on concrete durability performance, by measuring the electrochemical parameters (corrosion rate and corrosion potential) of the embedded reinforcing steel. To that effect, concrete specimens were exposed to the marine environments making a total of 21 test stations distributed among ten countries (Argentina, Bolivia, Chile, Colombia, Costa Rica, Mexico, Spain, Uruguay, Portugal and Venezuela). This paper presents the reinforcement electrochemical evaluation, which allows identifying its corrosion activation. The chloride ions concentration which induces the reinforcement corrosion is also presented, depending on the environment to which the concrete specimens were exposed.
