In this article, some of the physical, mechanical, and durability properties of mortars were evaluated. These mortars had partial replacements of the natural fine aggregate (NFA) with recycled fine aggregate (RFA) and carbonated recycled fine aggregate (CRFA) in amounts of 0%, 25%, and 50%. For this purpose, 3 groups of mortar mixtures were elaborated with a w/c ratio of 0.65. The results showed that an increase in the percentage of replacement of the CRFA, led to an improvement in the compressive strength of the mortar, as well as a lower superficial absorption rate. En este artículo, se evaluaron algunas de las propiedades físicas, mecánicas y de durabilidad de morteros preparados con reemplazos parciales de 0%, 25% y 50% del agregado fino natural (AFN) por agregado fino reciclado carbonatado (AFRC) y sin carbonatar (AFR). Para ello, se elaboraron 3 grupos de mezclas de mortero, con una relación a/c de 0,65. Los resultados obtenidos demostraron un aumento en la resistencia a la compresión del mortero y una menor tasa de absorción superficial, conforme se incrementó el porcentaje de reemplazo del AFRC.
