Resumen


En esta investigación se evaluó el efecto de la adición de ceniza de bagazo de caña (CBC) en la microestructura de morteros. La CBC fue tamizada durante 5 minutos a través de la malla No. 200 ASTM y evaluada mediante pruebas de análisis químico, difracción láser, absorción física de gases, Microscopia Electrónica de Barrido (MEB) y Difracción de Rayos X (DRX). Se elaboraron mezclas de mortero con 0, 10 y 20% de CBC como sustituto parcial del cemento manteniendo una relación agua/materiales-cementantes de 0.63. Se realizaron pruebas en estado fresco y pruebas de caracterización microestructural a través de MEB y DRX y de resistencia a la compresión a edades de 1, 7, 28, 90 y 600 días. Los resultados muestran que la adición de 10 y 20% de CBC decrementa la trabajabilidad de los morteros, sin embargo, mejora su microestructura e incrementa su resistencia a la compresión a edades tardías.
