Keywords:High temperature, Leaching, CT-XRD

To evaluate level of contaminated concrete in Fukushima Daiichi Nuclear Power Plant, it is important to grasp deterioration of concrete under the conditions at the beginning of disaster. This research evaluated alteration of cementitious materials due to elevated temperature and leaching using Non-Destructive Integrated CT-XRD Method.
