Abstract: Within the framework of a common DFG research project of the Institute of Building Materials research (ibac) of RWTH Aachen University and the Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University, the possible applications of cement-based concrete as a material of its own or as composite are developed for the field of machine tool manufacturing. Owing to the development in concrete technology during the last three decades, the properties of cement concrete could be significantly improved and in many fields, they reach or even exceed the level of polymer concrete which is presently applied as substitute material e. g. for steel or grey cast iron. Therefore, after the investigations performed within the framework of the research project, it shall be possible to apply cement concrete in machine tool manufacturing as substitute material for steel, replacing polymer concrete which is ecologically questionable because of its high percentage of epoxy resin. In this paper, results are presented for the fatigue behaviour of two different concrete types. For these studies, a novel test bench was required which is presented in detail. The design of the test bench allows performing various fatigue tests on cement-based concretes to be used for machine tools in a frequency range of about 200-500 Hz and force amplitudes of about 10 kN.
