Resumen


Se estudió la sustitución del árido normalizado por arena de fundición residual (WFS) sobre las propiedades físicas de morteros mediante ensayos de resistencia a la compresión y absorción capilar. El agregado fue reemplazado por WFS en su estado natural (WFS), arena de fundición residual lavada (WFSW) y arena de fundición residual tratada térmicamente (WFST). La WFS tenía porcentaje de bentonita, que se buscó activar térmicamente. Se encontró que el comportamiento físico de los morteros que contienen WFS y WFSW, fue similar al de la muestra control. A la arcilla recuperada del lavado de arena se le evaluó su potencial puzolánico, se encontró que, con el tratamiento térmico, la montmorillonita adquiere comportamiento puzolánico. Los morteros con WFST, presentaron una caída en la resistencia a la compresión. El efecto puzolánico logrado en la arcilla no se reflejó en la resistencia a la compresión de los morteros con WFST.
