Untersuchung von Transport- und Schaedigungsprozessen in Keramiken und mineralischen Baustoffen mit lokal und global angeregter aktiver Thermografie

摘要

In this report, the development of an active thermography method is presented, which enables time and spatial resolved in-situ and real time visualisation of transport and damage phenomena. The method can be applied in industry and environment. By using different thermal excitation sources, i. a. the thermal material properties of ceramics and dry and moist mineral building materials can be determined. Damage processes in ceramics can be visualised in-situ. Further on, data are presented which have been recorded during the capillary moisture rise inside sandstone.
