Hormigón de altas prestaciones basado en aglomerantes poliméricos

Abstract

Este trabajo de investigación aborda el estudio de un hormigón de altas prestaciones, formado por áridos naturales y un aglomerante orgánico constituido por una resina termoestable poliéster, denominado hormigón polimérico HP. Se describe el material a nivel microscópico y macroscópico, presentando sus propiedades físicas y mecánicas fundamentales, mediante diferentes técnicas experimentales, tales como: porosimetría de mercurio, microscopía electrónica (SEM-EDAX), difracción de rayos X (DRX) y ensayos mecánicos (módulo de elasticidad, curvas tensión- deformación y resistencias últimas). Como consecuencia del estudio experimental llevado a cabo, se ha podido apreciar cómo el HP está formado por porosidad cerrada del 4,8%, proporcionando una elevada continuidad a su microestructura interna, lo que justifica, en parte, la mejora de propiedades mecánicas respecto al hormigón tradicional, con unos valores medios de resistencia a compresión de 100 MPa y superiores a 20 MPa en su resistencia a flexotracción. Debido a la falta de estandarización, se ha concluido cómo el ensayo de flexión puede ser un procedimiento adicional al de compresión, a la hora de establecer las clases resistentes del HP.
