Abstract

This paper aims at finding the coupled effect of hot and humid environment on the corroded repaired patches of chloride contaminated steel reinforced concrete. Chloride induced corrosion under coupled environmental effects of high humidity and high temperature often found in gulf marine environment is a very serious threat for durability of reinforced concrete structures. In the previous research, the authors experimentally corroborated re-corrosion in the repaired reinforced concrete patches in the form of macro-cells. But, whether this formation of macro-cell is influenced by the coupled effect of high temperature and high relative humidity remained a question and formed the basis of this ..
