Resumen
Reciclar genera actividades que no dañan al medio ambiente por lo que tiene ventajas ecológicas y reduce la explotación de recursos renovables que se encuentran en agotamiento. Es una alternativa para la elaboración de hormigón en la construcción de estructuras con este nuevo hormigón pero puede afectar su durabilidad como su vida útil. Factores como la corrosión y la migración de cloruros son cusas que afectan a la estructura con hormigón elaborado con áridos reciclados. En el siguiente trabajo se evalúa la durabilidad de hormigones elaborados con 100% de árido reciclado encapsulado en la fracción de 5-9 mm con PZ, con respecto a hormigones elaborados con 100% de árido natural ambos amasado con P35 y colocados en tres diferentes sitios de exposición. Luego de realizado los ensayos se concluye el árido natural tiene un comportamiento superior que los hormigones elaborados con áridos reciclados pero no deja de ser una alternativa viable.
Recycling generates activities that do not harm the environment, so it has ecological advantages and reduces the exploitation of renewable resources that are depleted. It is an alternative for the manufacture of concrete in the construction of structures with this new concrete but it can affect its durability as well as its useful life. Factors such as corrosion and the migration of chlorides are causes that affect the structure with concrete made from recycled aggregates. In the following work the durability of concretes elaborated with 100% of recycled aggregate encapsulated in the fraction of 5-9 mm with PZ is evaluated, with respect to concretes made with 100% of natural aggregate both kneaded with P35 and placed in three different sites of exposition. After the tests were completed, the natural aggregate has a higher performance than the concretes made with recycled aggregates but it is still a viable alternative.
