Resumen
El hormigón es un material de uso frecuente en la construcción de viviendas y edificios en el Ecuador, por tal motivo se hace necesario el estudio y la mejora de sus propiedades con el fin de brindar calidad y seguridad en las construcciones.El hormigón es un material que por sí solo es muy frágil, necesita de aditamentos para la mejora de ciertas propiedades, como es la tenacidad. Para esto son muchos los materiales que se están estudiando, de esta lista sobresalen las fibras de acero, un material muy resistente también pero que hasta el momento solo se lo aplica para obras provisionales como revestimiento de túneles, taludes y pavimentos.Uso de los objetivos de este informe es brindar a través del conocimiento existente un aporte en cuanto al diseño de hormigón con fibras de acero para la mejora dela tenacidad ante esfuerzos de corte, en base a esto hemos estudiado las características de los agregados, la normativa existente para ensayar varias muestras que nos darán resultados para la evaluación de la tenacidad del hormigón en la ciudad de Guayaquil.Adicionalmente se estudian otras características del hormigón fresco y de la resistencia a la compresión y flexión (módulo de rotura), las cuales nos darán datos adicionales para mejorar nuestros diseños.
Concrete is a material often used in the construction of houses and buildings in Ecuador, for this reason the study and improvement of its properties in order to provide quality and safety in construction is necessary.Concrete is a material that alone is very fragile, adjuncts needs to improve certain properties, such as toughness. To this are many materials being studied, from this list you stands as steel fibers, also a very durable material, but so far only applies to temporary works as lining tunnels, embankments and pavements.Use of the objectives of this report is to provide through the existing knowledge a contribution in the design of concrete with steel fibers to improve the tenacity to shear stresses, on this basis we studied the characteristics of the aggregates, existing regulations to test several samples that will give us results for the evaluation of the toughness of concrete in the city of GuayaquilIn addition other characteristics of freshconcrete and compressive strength and bending (modulus of rupture) they are studied, which will give us additional data to improve our designs.
