Concrete that Cs penetration and leaching experiments simulating exposed to dry and wet environmental changes showed different behavior depending on the number of dry/wet cycles.In our study, the microstructure of concrete with different number of dry/wet cycles is observed using fluorescent epoxy resin to examine the details structural changes.
