Stochastic Assessment for Chloride Penetration in Reinforced Concrete Structures under Corrosive Environments

Article Preview

Abstract:

In the paper, the improved coupling convection and diffusion model of chloride ion penetration in reinforced concrete (RC) structures under corrosive environments is presented, in which many major influence factors such as environmental temperature and relative humidity, water ratio of concrete, and stress state etc are considered. Based on Fourth-Moment stochastic simulation theory, the estimation of the depassivation probability of reinforcement in corrosive RC is analyzed. And many important conclusions on depassivation of reinforcement is gained, which will be useful for repair, rehabilitation, and replacement of RC structures in corrosive environments.
