Estudio de la hidratación de pastas de cemento portland reemplazadas con escoria granulada de alto horno, ceniza volante y metacaolín: efecto del empleo de dos aditivos superplastificantes

Abstract

Este trabajo de investigación se enfocó en la evaluación del efecto que tienen diferentes materiales de reemplazo y dos aditivos superplastificantes en el desarrollo de las propiedades mecánicas, formación de fases y en la evolución del calor de hidratación de pastas de cemento portland reemplazadas hasta un 60%. Para esto se empleó ceniza volante, escoria granulada de alto horno, metacaolín y humo de sílice. Las mezclas fueron fabricadas con una relación agua/sólidos de 0.4, 0.3% de aditivo superplastificante e hidratadas durante 60 días. En base a los resultados se confirmó que con el uso de materiales de reemplazo, se redujo la cantidad de hidróxido de calcio, debido a la reacción puzolánica y se incrementó la resistencia a la compresión. Palabras clave: Reactividad, materiales cementosos suplementarios.

Keywords
