Abstract

La presente invencion se refiere a concreto, mortero y otras mezclas endurecibles que comprenden cemento y ceniza volátil para uso en construccion y otras aplicaciones, dichas mezclas endurecibles muestran niveles significativos de resistencia a sulfato y ácido mientras mantienen propiedades de resistencia a la compresion aceptables; las mezclas endurecibles resistentes a sulfato y ácido de la invencion que contienen ceniza volátil comprenden materiales cementosos y un agregado fino; los materiales cementosos pueden comprender ceniza volátil así como cemento; el agregado fino puede comprender ceniza volátil así como arena; la cantidad total de ceniza volátil en la mezcla endurecible varía de alrededor de 60% a aproximadamente 120% de la cantidad total de cemento, en poso, ya sea que la ceniza volátil se incluya como un material cementoso, un agregado fino o un aditivo o cualquier combinacion de los anteriores; en los ejemplos específicos, el mortero que contiene 50% de ceniza volátil y 50% de cemento en los materiales cementosos demostro propiedades superiores de resistencia a la corrosion.
