For the improvement of the load bearing behaviour and the useful properties of concrete structures which are subject to bending and tensile stresses a steel reinforcement is, in general, stipulated. For reasons of corrosion protection, the steel reinforcement requires a concrete cover with a thickness of several centimetres. The demand for corrosion-resistant thin-walled parts is a motivation for the application of alternative reinforcement materials. Within the scope of the Collaborative Research Centre “SFB 532“ (financed by the German Research Foundation DFG) the application of textiles made of polymer, carbon and alkali-resistant (AR) glass filaments in a fine concrete matrix are examined. In the long run it is the aim to reach the filament strength of the immersed textiles as thoroughly as possible. By reason of insufficient bond properties and damages which are a consequence of textile manufacturing processes, the utilisation of AR glass textiles in reinforced concrete components is approximately 30% under tensile load. Therefore the possibility of improving the activation of the filaments and thus the load bearing behaviour of textile reinforced concrete structures through the saturation of textiles and the modification of concrete with liquid polymers is discussed. Based on the accomplished tests, the utilisation of the textiles and the connected increase of the internal bond between the filaments duplicated the maximum component load-carrying capacity.
