Keywords:high temperature, Non-Destructive Integrated CT-XRD Method

What kind of alteration occurs when the concrete structure receives heating is evaluated from the viewpoint of microstructure by observation method centering on Non-Destructive Integrated CT-XRD Method. At that time, by comparing the samples of various conditions, we obtained knowledge concerning alteration and cracking of hydrate structure of concrete due to high temperature.
