The paper reports on the effect of fibre type, matrix workability, and mixer type on the distribution and opening of collated fibrillated polypropylene fibers used as concrete reinforcement. By means of the wash-out test method and within the limitations of the experimental program, it is demonstrated that: twisted fibers ere more likely to open than straight fibers in a zero-slump matrix, fiber distribution and opening is easier in a slumpable matrix than in a zero-slump matrix, and high-intensity mixers are more efficient than low-intensity ones even if they tend to shear a larger number of fibers. The investigation was limited to laboratory-type equipment.
