Abstract:	Der zunehmende Einsatz von Carbonbeton macht die Kenntnis der entsprechenden Materialkennwerte, v. a. das Verhalten unter Zugbeanspruchung, grundsätzlich erforderlich. Da bislang nur für wenige Bewehrungsmaterialien konkrete Bemessungskennwerte vorliegen, ist man häufig auf deren experimentelle Ermittlung angewiesen. Im Zuge der Weiterentwicklung der Materialien wurden in den vergangenen Jahren auch die Prüfmethoden wiederholt modifiziert. Die in einem gemeinsamen Forschungsprojekt von TU Dresden, RWTH Aachen und MFPA Leipzig erarbeitete Prüfempfehlung zur Bestimmung der Materialkennwerte bei Zugbeanspruchung von Textilbeton wird hier vorgestellt. Ergänzt sind praktische Empfehlungen zu Versuchsdurchführung und Vermeidung typischer Fehler sowie Hinweise zur Interpretation der Ergebnisse. Uniaxial tensile test for carbon reinforced concrete with textile reinforcement Due to the increasing use of carbon reinforced concrete, the relevant material characteristics - especially the tensile load bearing behavior - are essential knowledge. Often, design values have to be determined experimentally, as so far only few reinforcing materials are coming with specific recommendations. In the past years, test methods have been revised and modified repeatedly, following the advances in material development. In this paper, a test recommendation is presented for determining the tensile load bearing behavior of concrete with textile reinforcement, developed in a joint research project by TU Dresden, RWTH Aachen and MFPA Leipzig. In addition to the fundamental specifications, practical advices regarding the experimental procedure and avoidance of typical errors as well as essential notes on the interpretation of results are given.
