Abstract: Given the importance of standardization of the use of recycled aggregate and for the successful deployment and management of these aggregates in the civil engineering works, the UPV within the GEAR project, led by GERD, performs a quality assessment of recycled aggregates from construction and deconstruction waste and the requirements to be met if used in the production of no structural precast elements. At the laboratory level, equipment for the manufacture of waffle slab with recycled aggregate available in the market was designed in order to validate its use in prefabricated elements once an appropriate methodology on requirements and implementation of precasted elements was established. The quality of recycled aggregates and their effect on the quality of the final products was studied to establish a selection and classification of materials that can generate dosage criteria for the manufacture of waffle slab under vibro-compression parameters. From experiences with recycled aggregate from concrete precast industries it is verify that its use to produce no structural precast elements may conduce to very good results with similar results than in actual production with natural aggregates without any variation. The use of other recycles aggregates may be generalized but more researches are needed to validate this asseveration.
