Influence de la rhéologie des bétons renforcés de fibres métalliques sur leurs propriétés mécaniques
This paper presents the results of an experimental study on the effect of rheology on the orientation of steel fibers. It then studies then the influence of the orientation of a volume of 0.5% of steel fibers on the mechanical properties of a fluid ordinary concrete and a self-compacting concrete (low yield stress) and of a concrete with high performances figure (high yield stress). The results show that the fluidity of the concrete followed by the wall effects are essential parameters of the orientation and distribution of fibers. Since one obtains an orientation in the direction of the mechanical effectiveness, a flexural behavior clearly improved is observed, including for ordinary concrete. On the other hand, we observed in the case of a high performances concrete that a bad orientation of fibers cancels their mechanical contributions in bending (ductility). Compressive strength is not affected.
