Resum

Con un ritmo cada vez mayor, el plástico desechado ha llegado a ser uno de las preocupaciones del medio ambiente en el mundo. En este estudio, desechos de botellas plásticas de tereftalato de polietileno (PET) son usadas para producir fibras recicladas, las cuales se mezclaron con el concreto para producir muestras prismáticas. El desempeño a flexión, en términos de parámetros de resistencia y rigidez a flexión de muestras de concreto reforzado con diferente contenido de fibras de PET, fue obtenido por ensayos de especímenes bajo un arreglo de carga central. La rigidez a flexión fue determinada acorde al JSCE. También, elementos compuestos con fibras vírgenes y sin fibras (mezcla de control) fueron ensayados para realizar una evaluación comparativa. Los resultados sugieren que la adición de fibras de PET en el concreto generó similar o superior resistencia residual comparada con el concreto reforzado con fibras vírgenes. Sin embargo, el concreto con bajo contenido de fibras recicladas no es recomendado debido a su limitada resistencia residual y ductilidad.
