La producción de áridos de residuos mixtos reciclados genera un elevado contenido de partículas por debajo de 63 μm. Este material puede ocasionar un incremento de la demanda de agua, sin embargo, pueden contribuir a rellenar espacios entre los granos de cemento. El presente trabajo evalúa la influencia del material por debajo 63 μm de áridos reciclados mixtos en las propiedades de hormigones y morteros. La actividad puzolánica medida por calorimetría isotérmica fue muy baja. El uso del 6% del material en morteros incrementa la demanda de agua, ocasiona una reducción de la resistencia, pero disminuye la porosidad efectiva de la matriz e incrementa la densidad de la ITZ. Los ensayos de expansión por álcalis en morteros mostraron una reducción de la porosidad conectada de la matriz. La misma tendencia fue observada en el hormigón. La contribución beneficiosa de dicha fracción puede compensar los problemas en la reología y en las propiedades mecánicas.
