The main objective of this research work is to make a comparative analysis of a concrete pattern f'c = 210 kg/cm2 added with galvanized wire fibers in the form of barbed wire against another one added with galvanized wire fibers in a rectilinear form with hooks, taking as evaluation parameters the slump and tensile strength. The concretes were made with IP type Portland cement, fine aggregate from the Cunyac quarries (55%) and Vicho confitillo (45%), a coarse aggregate of ¾ “ from the Vicho quarry, as these were the chosen aggregates that fulfilled with the characteristics required by the Peruvian Technical Standards in the Manual of Tests of the MTC, galvanized wire fibers in the form of tines and rectilinear with hooks manufactured manually in percentages of 0.5%, 1.0%, 1.5%, 2.0% and 2.5% with respect to the total weight of the master mix, the concrete was designed with the ACI (American Concrete Institute) method. 144 cylindrical samples were made, which were subjected to tests of resistance to compression and traction (Brazilian test - Split Test) with the inclusion of galvanized wire fibers in the form of barbs and rectilinear with hooks manufactured manually in percentages of 0.5%, 1.0 %, 1.5%, 2.0% and 2.5% regarding the total weight of the master mix, quantities that were considered reasonable for the research, based on the Technical Manual for the use of fibers as a structural reinforcement of MACAFERRI; In the same way, the influence of these galvanized wire fibers on the slump of concrete, studied through the Cone de Abrams, was considered. The results obtained with the inclusion of galvanized wire fibers in the form of barbs at 2.0% and in a rectilinear form with hooks at 1.5% showed a better tensile behavior for the 07, 14 and 28 days of curing. In conclusion, the replacement with galvanized wire fibers in the form of barbs and rectilinear with hooks at 2.0% and 1.5% respectively, depending on the total weight of the master mix, result in a better tensile behavior and it was also determined that while more percentage of fibers is added in both cases the consistency of the mixture tends to become dry.
