Chloride Ion Erosion in Concrete under Sustained Axial Pressure

摘要

Reinforcement corrosion is one of the leading factors influencing the durability of concrete structure. Erosion of chloride ions on the concrete structure is influenced by many factors. This article carried on an experimental study on the rules of chloride ion penetration under the sustained axial compression after different corrosive time, when the concrete is corroded under the joint action of axial compression load and chlorine salt circulation. The results proved that, with the increase of the intensity of load and the cycle time of chlorine salt, the number of chloride ion ingress in concrete continues to increase. The experimental results may provide a reference to the durability design of concrete in chloride environment.
