However, its mechanical performance is very useful in the construction of reinforced concrete structures. This article describes and discusses the results of an experimental research, which reflects the chloride ion effects at a short term, on the durability properties of concrete reinforced with RC-65-35-BN steel fibers using dosages of 30 and 60 kg/m3. In order to predict the effect of chloride ion on the steel fiber reinforced concrete, trends of corrosion were estimated during 56 days by half-cell potential and linear polarization resistance tests. Additionally, the surfaces of the steel fibers were analyzed by X-ray diffraction with the purpose to determinate the corrosion products that were generated. The obtained results demonstrates an adequate performance of the fibers embedded in the concrete for this phase of corrosion initiation, due to its low probability of corrosion.]]></p></abstract>

Sin embargo, su desempeño mecánico es muy útil en la construcción de estructuras de concreto reforzado. Este artículo describe y discute los resultados de un estudio experimental que refleja el efecto del ion cloruro a corto plazo, sobre las propiedades de durabilidad del concreto reforzado con fibras de acero RC-65/35-BN usando dosificaciones de fibra de 30 kg/m3 y 60 kg/m3. Con el fin de predecir el efecto del ion cloruro sobre el concreto reforzado con fibras de acero, las tendencias de la corrosión se estimaron durante 56 días mediante ensayos de potencial de media celda y resistencia a la polarización lineal. Adicionalmente, las superficies de las fibras de acero se analizaron por difracción de rayos X con el propósito de determinar los productos de corrosión generados. Para esta fase de iniciación de la corrosión, los resultados obtenidos demuestran un adecuado desempeño de las fibras embebidas en el concreto debido a su baja probabilidad de corrosión.]]></p></abstract>
