Temperature and humidity influences on the on-site active marine corrosion of reinforced concrete elements

Abstract

Reinforcement corrosion is a main durability issue for reinforced concrete structures in the marine environment. Environmental actions on the corrosion rate have been documented by several researchers on actively corroding reinforced concrete structures. Therefore, considering the influences of ambient temperature and relative humidity is very important for prospective studies of corroding structures. In this paper, active corrosion of concrete members in the marine environment was observed for 4.8 years, and a relationship between the corrosion rate and ambient temperature and relative humidity is modeled. This very simple proposal is presented as a complementary tool to experimental measurements when assessing the deterioration rate of concrete structures in the marine environment.
