Abstract:
To enable a widespread industrial application of carbon reinforced concrete, a reliable characterization of material properties, such as the tensile strength and bond behavior of the composite material, has been established using standard test methods. To allow for an even wider range of application, the fatigue behavior and corresponding appropriate test methods were examined in this paper. A test method along with an experimental setup for determining both static and cyclic tensile behavior is presented. Test results using the proposed methods are shown and discussed. Based on the results of cyclic tests of a reference load combination, load frequency as well as load level were varied and their influence is documented in this paper. Finally, the temperature development during cyclic tests is documented for one test specimen. Based on these results, future research opportunities are presented.
