Effect of recycled aggregate on physical-mechanical properties and durability of vibro-compaction dry-mixed concrete hollow blocks Martín Morales, María Cuenca Moyano, Gloria María Valverde Espinosa, Ignacio Valverde Palacios, Ignacio Construction and demolition waste Recycled aggregate Technological nutrient Precast blocks This paper deals with the feasibility of using fine and coarse recycled aggregates, both from concrete and mixed sources, as technological nutrients for the production of vibro-compacted dry-mixed concrete hollow blocks traditionally used in wall construction. Five series of blocks were prepared with different combinations of concrete and recycled aggregates and a reference one to be used as a control series. The results shows that the incorporation of recycled aggregates does not compromise compliance with the European standard EN 771-3, nor further durability requirements by means of hazardous ambient such as freeze-thawing and salts crystallization and the value declared by the manufacturer. 2026-02-25T10:44:09Z 2026-02-25T10:44:09Z 2017-04-11 journal article Published article: Martín-Morales, M., Cuenca-Moyano, G.
