description El presente artículo de reflexión tiene como objetivo principal demostrar las cualidades del concreto con adición de fibras, tomando como base estudios realizados en torno a este material, permitiendo manejar una amplia recopilación de resultados para así permitir dar una opinión crítica desde diferentes ámbitos relevantes en la ingeniería civil. El concreto, al ser uno de los materiales más utilizados en las construcciones civiles, plantea la necesidad de mejorar sus propiedades, mejorando así las edificaciones en las cuales utilizaremos este material. El concreto fibroreforzado es un material que se ha utilizado años atrás para algunas construcciones. Actualmente, ha demostrado excelentes resultados tanto desde el punto de vista estructural como económico, a corto y largo plazo. Tendrá como enfoque analizar las cualidades ambientales, económicas y estructurales del concreto fibroreforzado, sustentándose en la experiencia propia adquirida en años de experiencia desempeñando labores profesionales en construcciones civiles. Con esto, cada argumento se respaldará con dicha experiencia, lo que permitirá contextualizar su aplicación a diferentes áreas del entorno constructivo del país.

It provides a broad collection of results and allows for critical opinions from various relevant fields in civil engineering. Concrete, as one of the most widely used materials in civil construction, raises the need to improve its properties, thereby enhancing the buildings in which it will be used. Fiber-reinforced concrete is a material that has been used for several years in some construction projects. Currently, it has demonstrated excellent results from both the structural and economic perspectives, both in the short and long term. The focus will be on analyzing the environmental, economic, and structural qualities of fiber reinforced concrete, based on my own experience gained over years of professional work in civil construction. Each argument will be supported by this experience, which will allow its application to be contextualized in different areas of the country's construction sector.PDFhttp://creativecommons.org/licenses/by-nc-nd/2.5/co/Atribución-NoComercial-SinDerivadas 2.5 Colombiainfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Concreto FibroreforzadoPropiedades EstructuralesSostenibilidad.Fiber-reinforced concreteStructural propertiesSustainabilityIngeniería civil --- Sostenibilidad --- ColombiaConcreto Fibroreforzado: una mirada integral a sus tipos, ventajas y aplicacionesFiber-reinforced concrete: a comprehensive look at its types, advantages, and applicationsTesis de Pregradohttp://purl.org/coar/resource_type/c_7a1finfo:eu-repo/semantics/bachelorThesisACI 318.
