Concrete that Cs penetration and leaching experiments simulating exposed to the environment changes like dry and wet showed different behavior depending on the number of dry-wet cycles. In our study, the structure of concrete with different number of dry-wet cycles is observed physically or chemically, and then the details is investigated.
