Damage in concrete grows due to the environmental effects. For detailed inspection of concrete damages, unconfined compression tests have been frequently conducted, taking out core samples. However, the mechanical properties are not good enough for practical evaluation of damage degree in concrete materi- als. The concrete damages are affected by inner crack distribution. In this study, the crack distributions of core samples were inspected with X-ray computed tomography method. The core-samples were collected from a water canal of reinforced concrete, which is strongly influenced by freeze and thawed process. The * concrete damage was evaluated by DeCAT in core tests. Thus, the durability index E /E calculated from 0 DeCAT are clearly correlated with CT characteristics identified by X-ray computed tomography method.
