Effects of water to cement ratio, recycled fine aggregate and air entraining/plasticizer admixture on masonry mortar properties Cuenca Moyano, Gloria María Martín Pascual, Jaime Martín Morales, María Valverde Palacios, Ignacio Zamorano Toro, Montserrat Construction and demolition waste Recycled fine aggregate Masonry mortar Air entraining/plasticizer admixture ANOVA The main aim of this study has been to determine the influence of total water to cement ratio, recycled fine aggregate from construction and demolition waste, and air entraining/plasticizer admixture on the properties of masonry mortar. Two mortar series were prepared using varying percentages of dry or pre-soaked recycled fine aggregate to replace natural fine aggregate, and four different dosages of air entraining/plasticizer admixture. Data were analysed using three-way and one-way ANOVA, in order to determine the effect of the factors and to compare the means of the mortars manufactured. The results showed the technical feasibility of masonry mortars manufactured with up to 100% of recycled fine aggregate. In addition, total water to cement ratio was the most determining factor for consistency, dry bulk density, and compressive and flexural strength; the recycled fine aggregate for bulk density; and the air entraining/plasticizer admixture for air content and capillary water absorption coefficient. 2026-01-14T11:25:16Z 2026-01-14T11:25:16Z 2019-09-16 journal article Published version: G.M.
