Uso de residuos de construcción y demolición como material cementicio suplementario y agregado grueso reciclado en concretos autocompactantes

Abstract

En los últimos años, el uso del concreto autocompactante (CAC) ha ido aumentando desde su inicio, debido a la capacidad que tiene para llenar encofrados con alta densidad de aceros, por lo que el empleo de este tipo de concreto en la elaboración de muros delgados armados sería una solución al llenado incompleto de este tipo de elementos prefabricados. Por otra parte, el empleo de residuo de mampostería (RM) y agregado grueso reciclado de concreto (AGR) proveniente de residuos de construcción y demolición (RCD) como reemplazo del cemento (20 % en volumen) y del agregado grueso, respectivamente, daría un enfoque sostenible al concreto autocompactante. El objetivo de este estudio fue evaluar la influencia de los RCD en las propiedades en estado fresco (flujo de asentamiento, embudo en V y caja en L) y estado endurecido (resistencia a la compresión, tracción indirecta y compresión diagonal de muretes) de concretos autocompactantes. Las mezclas de CAC propuestas muestran que cuando se sustituye el cemento Portland y el agregado natural por RM y AGR, respectivamente, los concretos pueden satisfacer los requerimientos de las directrices europeas de European Federation of National Associations Representing producers and applicators of specialist building products for Concrete (EFNARC por sus siglas en inglés). En estado endurecido, los CAC con RCD lograron un desempeño aceptable en comparación con la mezcla de referencia (CAC-referencia). Todas las mezclas lograron una resistencia a la compresión superior a los 21 MPa (28 días), adecuada para muros divisorios de casas, de acuerdo al Reglamento Colombiano de Construcción Sismo Resistente (NSR 10).
