Quality control of recycled aggregates (RAs) from construction and demolition waste (CDW) Martín Morales, María Zamorano Toro, Montserrat Valverde Palacios, Ignacio Cuenca Moyano, Gloria María Sánchez Roldán, Zoraida Recycled aggregate Quality control Classification Various studies have shown that recycled aggregate (RA) can be used to make new concrete. However, in the same way as with natural aggregate (NA), RA also needs to be assessed in terms of grain- size distribution, absorption, abrasion, etc., for it to comply with national standards. In order to evaluate the use of RA, standards and guidelines from 16 countries have been analyzed and compared to determine the most important quality criteria for the physical and mechanical properties of concrete. The results of this analysis have led to the proposal of the set of recommendations included in this chapter. 2026-02-25T10:58:35Z 2026-02-25T10:58:35Z 2014-03-27 book part Published version: Martín-Morales, M., Zamorano, M., Valverde-Palacios, I., Cuenca-Moyano, G.
