Abstract: In the past, the tensile strength of textile reinforced concrete was increased by the number of textile layers thus enabling the application in load-bearing structures. To improve the serviceability and to further minimise crack widths ductile matrices are used. Therefore, short fibres of different materials (glass, carbon, steel, synthetics) are added to the mix in different amounts. The fibres complement each other and improve the post-cracking behaviour of the fine grained concrete bridging cracks. Furthermore, they increase the tensile strength. As the addition of short fibres affects the flowability of the concrete, which must, however, be ensured, fine grained concrete mixes without fibres are modified to guarantee workability when fibres are added. In this paper, the influence of fibre content and fibre length as well as the post-crack behaviour in bending tests are described.
