| Summary: | <p>Taking into account the few studies carried out about hot-dipped galvanized reinforcements, this work aimed to study the behaviour of these reinforcements in different alkalinity media and subjected to subsequent carbonation. For this purpose, galvanized and carbon reinforcements were immersed in alkaline solutions and electrochemically monitored to evaluate their behaviour. Results show that galvanized reinforcements present good performance in carbonated media and also in media with pH lower than 13.3, which presented corrosion potential under levels that indicate a passive state of reinforcementsregarding corrosion. On the other hand, carbon reinforcements present corrosion activity in carbonated media and passive condition in medias with pHs over 12.5.</p> |
