%X Rheological research works investigate for fire case the material behavior of small specimens and derive from the test results material laws to determine the behavior of structural elements due to fire exposure. However, as it is known, the heat and mass transport processes can significantly happen in different phases in macro concrete elements. Besides, in case of a fire, different heating rates occur in the cross section of structural elements. The validity of the transferred test results from small test specimens to the material behavior of structural elements indicates a phenomenon, which has not been investigated up to now. Such a research work has been done for the first time through close cooperation of subprojects A and B3 of SFB (Sonder-ForschungsBereich: A special fire research activity for structural elements in Braunschweig Technical University, 1971-1986). The results of the rheological investigations presented in this paper can lead to a new research conception about the determination of realistic fire behavior of concrete structures. By means of further purposive research work, it will be possible to reproduce the structural behavior in case of fire with simple but realistic mathematic-rheological relationships
