Resumen
En este Trabajo de Final de Grado, se ha estudiado la viabilidad del desarrollo de geopolímeros basados en chamota
(70-40 % en peso) activados con activador alcalino alternativo, cenizas volantes de orujillo (30-60 % en peso). Se ha
estudiado las propiedades físicas, mecánicas y térmicas de geopolímeros curados a 80 oC durante un día. Además,
se han fabricado como control geopolímeros basados en chamota activados con disoluciones de KOH comercial 4
y 8 M. Los resultados obtenidos demuestran que los cementos fabricados a partir de chamota activados con cenizas
volantes de orujillo como activador alcalino alternativo, presentan propiedades mecánicas, físicas y térmicas,
similares y en algunos casos superiores a los que emplean el hidróxido de potasio como activador comercial,
destacando los obtenido para la mezcla 40% chamota y 60% cenizas volantes de orujillo alcanzando una resistencia
a compresión de 11.6 MPa tras 28 días de curado.
In this Final Degree Project, the feasibility of the development of geopolymers based on chamotte (70-40 wt.%) activated with an alternative alkaline activator, pomace fly ash (30-60 wt.%), has been studied. The physical, mechanical and thermal properties of geopolymers cured at 80 oC for one day have been studied. Additionally, geopolymers based on chamotte activated with 4 and 8 M commercial KOH solutions have been manufactured as control samples. The results obtained demonstrate that the cements manufactured from chamotte and olive pomace fly ash as an alternative alkali activator exhibit mechanical, physical, and thermal properties that are similar, and in some cases superior, to those employing potassium hydroxide as a commercial activator. Notably, the mixture comprising 40 wt.% chamotte and 60 wt.% olive pomace fly ash achieved a compressive strength of 11.6 MPa after 28 days of curing.
