Resumen
El presente estudio tiene como finalidad la comparación entre el hormigón convencional y un hormigón con fibras PET de 5cm de largo, para este proyecto se consideró un módulo de rotura de 4.2MPa, se realizó el análisis del comportamiento a los 7, 14, y 28 días del hormigón convencional y mejorado mediante cilindros y vigas, los cuales fueron evaluados a flexión y compresión respectivamente. Se pudo observar que a los 28 días los dos diseños alcanzaron su resistencia requerida con la observación que en el ensayo de compresión el hormigón convencional obtuvo mayor resistencia en comparación al convencional, mientras que a flexión el hormigón mejorado con fibras PET obtuvo mayor resistencia que el hormigón convencional.
Se realizó el diseño del pavimento rígido para el hormigón convencional y el hormigón mejorado con fibras PET, se llegó a la conclusión que pese al incremento de su resistencia de diseño al utilizar fibras PET no se obtuvo variación en los espesores de losa, debido a los valores de módulo de rotura y elasticidad del concreto los cuales fueron similares para el hormigón convencional y mejorado.
Esta propuesta surge debido a la necesidad de concientizar acerca de la contaminación producida al medio ambiente en el proceso de elaboración de hormigones, lo cual se optó por utilizar el plástico PET, este se puede conseguir fácilmente mediante la recolección de botellas.
The purpose of this study is to compare conventional concrete and a concrete with 5cm long PET fibers, for this project a breaking modulus of 4.2MPa was considered, the behavior analysis was carried out at 7, 14, and 28 days of conventional and improved concrete by means of cylinders and beams, which were evaluated in flexión and compression respectively. It was observed that at 28 days the two designs reached their required strength with the observation that in the compression test the conventional concrete obtained greater resistance compared to the conventional one, while in bending the concrete improved with PET fibers obtained greater resistance than the conventional concrete. Conventional concrete. The rigid pavement design was carried out for conventional concrete and improved concrete with PET fibers, it was concluded that despite the increase in its design resistance when using PET fibers, no variation was obtained in the slab thicknesses, due to the values of modulus of rupture and elasticity of concrete, which were similar for conventional and improved concrete. This proposal arises due to the need to raise awareness about the pollution produced to the environment in the process of making concrete, which was chosen to use PET plastic; this can be easily achieved by collecting bottles
