This study is the result of investigating the relationship between the repetitive action conditions of compressive stress within the elastic limit and the salt penetration of concrete members. The salt water submergence test, ultrasonic velocity test, and compressive strength test on the concrete specimens were performed after repeatedly applying compressive stress on it. As a result of the test, it was clarified that an increase in the compressive stress and the number of repeated stress application within the elastic limit decreased the salt penetration velocity. This indicates that repeated stress application within the elastic limit has a significant effect on salt penetration velocity.
