Caracterización superficial de distintos materiales de construcción

Abstract: RESUMENEn este trabajo se ha realizado la caracterización de la superficie de diferentes materiales de construcción (már-mol, arenisca, granito y ladrillo) mediante cromatografía inversa gas-sólido a dilución infinita. La energía superficial se puede dividir en dos componentes: dispersiva y ácido-base. Los valores obtenidos para la energía dispersiva son bastante parecidas para mármol, granito y ladrillo, mientras que el valor más alto corresponde a la arenisca. Además, este material presenta una menor variaci… Show more

“…As these authors themselves pointed out, however, values depend on the nature, origin and composition of the surface in question, as well as on whether the interaction takes place in higher (crystal vertices) or lower (crystal planes) energy sites.After limestone, granite was the material with the highest dispersive component of the surface energy. The 44.13 mJ/m 2 (60ºC) exhibited by the stone studied here was in between the value reported for another variety, 29.38 mJ/m 2 (60 ºC)[28], and for a…”
