Resumen
En este trabajo Final de Máster, se ha estudiado la viabilidad del desarrollo de geopolímeros constituidos por cenizas volantes de orujillo (30-50 % en peso), como activador alcalino alternativo y escorias siderúrgicas de alto horno (70-50 % en peso), como fuente de aluminosilicatos, con el objetivo de fabricar materiales de construcción alternativos al cemento Portland. Se han determinado sus propiedades físicas, mecánicas y térmicas y comparado con las de geopolímeros de escorias que emplean soluciones activantes comerciales KOH (4M y 8M).
Los resultados obtenidos han permitido demostrar que las propiedades de los geopolímeros de escorias
activados alcalinamente empleando cenizas de orujillo, presentan propiedades superiores a cuando las
escorias son activadas por disoluciones activantes comerciales, disoluciones de KOH. Por tanto, se ha
demostrado la viabilidad del uso de cenizas de orujillo como potencial activador alcalino en la fabricación de materiales activados alcalinamente, presentando los nuevos materiales sostenibles obtenidos, ventajas económicas y medioambientales importantes.
In this Master's thesis, the feasibility of the development of geopolymers consisting of orujillo fly ash (30-50 wt %), as an alternative alkaline activator and blast furnace slag (70-30 wt %), as a source of aluminosilicates, has been studied with the aim of manufacturing alternative construction materials to Portland cement. Their physical, mechanical and thermal properties have been determined and compared with those of slag geopolymers using commercial KOH activating solutions (4M and 8M). The results obtained have demonstrated that the properties of alkaline activated slag geopolymers using orujillo ashes, show superior properties than when the slags are activated by commercial activating solutions, KOH solutions. Therefore, the feasibility of using orujillo ashes as a potential alkaline activator in the manufacture of alkaline activated materials has been demonstrated, presenting the new sustainable materials obtained, with important economic and environmental advantages.
