This paper presented the results of an experimental campaign whose ultimate goal was to produce high-performance self-compacting concrete (SCC) using recycled aggregates (RA) from the precast industry. The results of the fresh-state and mechanical properties tests performed on six concrete mixes (using RA from the precast industry) were presented. The first concrete mix is a reference mix using natural aggregates only (100% NA), and the remaining five mixes had various contents of fine (FRA) and coarse (CRA) recycled aggregates in concrete\u2019s composition: (2) 25\/25% (25% RA); (3) 50\/50% (50% RA); (4) 100\/100% (100% RA); (5) 0\/100% (100% CRA); (6) 100\/0% (100% FRA). The results showed that the high-performance concrete mixes with RA from the precast industry performed worse than the reference mix. However, taking into account all the mechanical properties studied, it can be concluded that RA from precast concrete elements are of very good quality and can be incorporated in the production of high-performance SCC. The potential demonstrated by the combined use of fine and coarse recycled aggregates was also emphasized. This type of work is expected to effectively contribute to raise awareness among the various players in the construction industry, particularly in the precast concrete industry, to the feasibility of using RA in significant quantities (notably coarse aggregates) and to the safety needed to assume structural functions, even for applications where high performance is required.<\/jats:p>","DOI":"10.3390\/ma12213565","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T05:18:26Z","timestamp":1572499106000},"page":"3565","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Fresh-State and Mechanical Properties of High-Performance Self-Compacting Concrete with Recycled Aggregates from the Precast Industry"],"prefix":"10.3390","volume":"12","author":[{"given":"Tiago","family":"Barroqueiro","sequence":"first","affiliation":[{"name":"Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1649-004 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8770-8439","authenticated-orcid":false,"given":"Pedro R. da","family":"da Silva","sequence":"additional","affiliation":[{"name":"CERIS, Instituto Superior de Engenharia de Lisboa, Instituto Polit\u00e9cnico de Lisboa,\r\n1500-310 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6766-2736","authenticated-orcid":false,"given":"Jorge de","family":"de Brito","sequence":"additional","affiliation":[{"name":"CERIS, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1649-004 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,30]]},"reference":[{"key":"ref_1","first-page":"648","article-title":"Elasticity and drying shrinkage of recycled aggregate concrete","volume":"82","author":"Hansen","year":"1985","journal-title":"Am.
