In this work, the use of steel fibers obtained from recycled tires has been proposed, as an alternative to increase the resistance of the concrete slab against flexo tracción efforts, and thus be able to mitigate the formation of cracks caused by the action of external loads, specifically in the design and construction of pavements. To this end, a study of the mechanical behavior of steel fiber reinforced concrete was carried out, which were previously obtained from the recycling of used tires, which in turn were obtained from retreads from different parts of the city of Lima. A series of cylindrical and prismatic specimens (concrete beams) were prepared, which were subsequently cured by flooding in a pool for periods of 3 days, 14 days and 28 days. In order to be able to evaluate the evolution of concrete resistances over time, the specimens were analyzed at different ages, these were specifically 3, 7 and 28 days. The results obtained show that the steel fibers had a direct effect on the flexo tracción modulus of rupture, achieving average increases of up to 48%, with a dosage of 3% of steel fibers by weight. providing a structural contribution to hydraulic concrete slabs. Finally, it was found that it is possible to obtain slabs with tensile bending strengths equivalent to slabs of smaller thicknesses, by applying steel fibers from recycled tires.
