Abstract:
A study regarding the structural behavior of four three-dimensional, full-scale, recycled-aggregate concrete frame structures was carried out. This paper describes the final tests, which consisted of destructive horizontal tests, with incremental monotonic loading, in accordance with a pushover analysis. The test structures had a varying content of coarse recycled aggregates (0%, 25%, 100%, and 100% with high-range water-reducing admixture—in overall volume of coarse aggregates). These aggregates were generated from the concrete precasting industry—that is, they are high quality and their negative effect on the recycled aggregate concrete mixtures was not expected to be significant. The four structures had the same geometry and reinforcement layout, and their design complied with Eurocode 2, Eurocode 7, and Eurocode 8. All the structures exhibited a ductile behavior, and their behavior was not significantly affected by the incorporation of recycled aggregates. There were also no differences in the cracking response. To the authors’ best knowledge, this is the first time that such experiments were made in full-scale recycled-aggregate concrete structures.
