	Summary:
	Fire can cause damage in concrete structures. The level of damage depends on several factors like maximal temperature, duration of fire, constituents of concrete etc. We have to design buildings for fire and deal with the possible reconstruction after a fire case if it happens. Both require special knowledge and special characterization. For reconstruction purposes it is very important to determine the level of damage and the necessary steps after fire. If the building can be renovated, non-destructive test methods are of high importance in analysis of actual damages. For the analysis of fire damage we applied by laboratory a new test method: the computer tomography (CT) method. The method is applicable because the density and porosity values in function of temperature are changed.
