Abstract: The this study we discusses use of polypropylene fibers to disperse reinforcement of fine-grained concrete. We made experimental studies on composite samples of fiber concretes binder. We find the optimum percentage of particulate reinforcement fine concrete polypropylene fibers equal to 4 kg/m3. This is due to the fact that further increase in the percentage of particulate reinforcement gives a slight increase in performance and in some cases and their reduction by reducing the thickness of the concrete layer so that the material exhibited a tendency to delamination.
