The postcracking behaviour of fibre reinforced concrete is particularly influenced by the fibre distribution and the fibre orientation. One could suppose that in self-compacting fibre reinforced concrete (SCFRC) fibres orient along the flow due to the wall-effect, the flow direction and the velocity profile in the concrete. To investigate the fresh and hardened characteristics (mechanical properties, orientation and distribution of the fibres) of SCFRC and to relate them to those of traditionally vibrated fibre reinforced concrete (TFRC), a research program is set up. The following parameters are investigated: fibre length, concrete flow distance and concrete type (SCFRC and TFRC).
