Resumen
The construction sector is one of the main consumers of raw materials and generates a high volume of waste within the European Union. The search for new materials that are more sustainable and respectful of the environment has become a challenge for countries with a high degree of industrialization. In this work, a study of the most relevant properties of masonry mortars made with recycled aggregates and reinforced with synthetic fibers was carried out. Three types of aggregates were used—natural, concrete recycling and ceramic recycling—and two types of reinforcing fibers: polypropylene and polyolefin. In this way, various tests of physical-mechanical characterization and a statistical analysis of the results were carried out. It has been shown that the mortars made from aggregate recycled concrete and reinforced with polypropylene fiber are the ones with the best properties for application in the construction sector, although without improving the properties of traditional mortars made from natural aggregate and without fibers.
El sector de la construcción es uno de los principales consumidores de materias primas y genera un alto volumen de residuos dentro de la Unión Europea. La búsqueda de nuevos materiales más sostenibles y respetuosos con el medio ambiente se ha convertido en un reto para los países con un alto grado de industrialización. En este trabajo se realizó un estudio de las propiedades más relevantes de los morteros de albañilería elaborados con áridos reciclados y reforzados con fibras sintéticas. Se utilizaron tres tipos de áridos —natural, hormigón reciclado y reciclado cerámico— y dos tipos de fibras de refuerzo: polipropileno y poliolefina. De esta forma, se realizaron diversas pruebas de caracterización físico-mecánica y un análisis estadístico de los resultados.
