The effect of PET fiber length on tensile strength for 1% and 2% reinforcement rates, shows an increase for sand concretes having fiber lengths of 10mm compared to the pure matrix, followed a reduction for concrete reinforced with longer fibers of 20mm. The best compressive strengths are obtained by adding PET PB and PET fiber at 1%. The best compressive strengths are obtained by adding PET PB and PET fiber with a length of 10 mm. The comparison of the failure mode of the fiber sand concrete shows that the latter have a ductile character during the break, that is to say that the specimen remains attached by the PET fibers after the break and no glow.
