Resumen
Este trabajo tiene como fin mostrar una alternativa para mejorar el comportamiento del hormigón convencional con la adición de fibras de polipropileno y fibras metálicas para el diseño de un pavimento rígido f´c = 350 kg/cm². Los progresos con los que aportan las fibras son la disminución de fisuras, el aumento considerable de la resistencia a Tracción, así como el incremento de otras propiedades. Con la búsqueda de beneficios adicionales en lo que se refiere a incremento de la durabilidad y reducción del refuerzo tradicional, las fibras son colocadas en aplicaciones estructurales. Debido a las nuevas preferencias constructivas el uso de hormigón reforzado con fibra avanza a gran velocidad, en el campo de los hormigones especiales se establece como una de las innovaciones más relevantes. Cada vez más se emplea el uso de hormigón fibro-reforzado, se utiliza en diferentes obras civiles, desde pavimentos rígidos hasta en el reforzamiento de estabilidad de obras subterráneas, estabilización de taludes y ejecución de piscinas. La visión de la investigación es comparar los resultados obtenidos en el diseño de hormigón simple y el hormigón reforzado con fibras, tomando en cuenta la metodología de diseño, procedimiento constructivo y precios unitarios.
This work aims to show an alternative to improve the behavior of conventional concrete with the addition of polypropylene fibers and metal fibers for the design of a rigid pavement f'c = 350 kg / cm². The advances with which the fibers contribute are the decrease of cracks, the considerable increase of the resistance to traction, as well as the increase of other properties. With the search for additional benefits in terms of increased durability and reduction of traditional reinforcement, the fibers are placed in structural applications. Due to the new constructive preferences, the use of fiber reinforced concrete advances at high speed, in the field of special concretes it is established as one of the most relevant innovations. The use of fiber reinforced concrete is increasingly used, it is used in different civil works, from rigid pavements to the reinforcement of stability of underground works, stabilization of slopes and execution of swimming pools. The vision of the research is to compare the results obtained in the design of simple concrete and fiber reinforced concrete, taking into account the design methodology, construction procedure and unit prices.
