Description
En este proyecto inicia con la fase I, con el desarrollo y la caracterización de un concreto de alto de rendimiento, resistencia a la compresión de 50 MPa, con fibra metálica y mesocarpio de coco en sustitución de refuerzo del 4 % en volumen de fibras metálicas y de coco. El material se dosificará utilizando un modelo de mezcla sin adición de fibra. Para la fase II, se estudiará el comportamiento por cortante de la losa alveolar pretensada, mediante análisis numérico, donde los parámetros necesarios para el modelado computacional basados en la mecánica de fractura no lineal, notablemente en la energía específica de fractura (Gf), que se determinaran en el laboratorio. Será estudiado, en el software comercial de ANSYS (APDL), una losa alveolar pretensada hipotética y la losa parametrizada del ensayo, para analizar los beneficios introducido por el material desenvuelto en comparación con un concreto no fibroso y haciendo análisis de los resultados obtenidos en el modelo experimental y en la modelación numérico. Resaltándose que las losas alveolares, en vista del proceso constructivo de extrusión, no permiten la introducción de refuerzo transversal, el problema simulado corresponde al ensayo típico de cortante. Este proyecto tiene el fin de innovar en la Investigación y en la aplicación al desarrollo tecnológico de la construcción, usando materiales no convencionales en losas alveolares pretensadas, que pueden generar gran impacto económico a las problemáticas de vivienda a nuestro país, principalmente en las zonas rurales, por las ventajas que presenta este tipo de elemento estructural.
