Abstract

One of the main causes of reinforced concrete degradation is chloride-induced corrosion. Chloride-induced corrosion depends on many factors like properties of the material, loading on the structure and environmental condition. There is much research on the deterioration of concrete structures over the years; but there is relatively little research on changing climate affecting the deterioration, which is the topic of this paper. The present study is purely analytical wherein conceptual T-Beam bridge girder has been taken for the prediction of time to corrosion initiation and corrosion propagation, incorporating effect of climatic condition. For comparison, eight study locations are selected. Corrosion initiation time is predicted for each location considering the climatic data of the corresponding location. With the variation in the temperature and relative humidity data at different study location, large variation in corrosion initiation time is found.
