A research program launched at TU Wien is combining ultra-high performance concrete (UHPC) and textile reinforcement made of carbon fibres to develop sustainable, material fitting building constructions. As a result the overall concrete mass can be reduced significantly and the durability of the structural members can be increased. In this context, the authors of this paper designed a hollow slab element exclusively reinforced with carbon textile reinforcement. To investigate the structural behaviour of this hollow slab elements, a test series was planned and carried out includ-ing 3-point bending tests and 4-point bending tests. While the bearing capacity is high and a good utilization of the material properties could be reached, failure modes like delamination, which are not well known from ordinary RC beams, could be observed.
