Structural use of fiber-reinforced self-compacting concrete with recycled aggregates: Case study of a foundation wall in Spain

This paper is focused on the use of mixed recycled-aggregates (RA), replacing 100% natural coarse aggregates, for producing steel fiber reinforced self-compacting concrete (FR-SCC-RA) oriented to construction foundation walls. To this end, an extensive experimental program dedicated mechanical characterization FR-SCC-RA walls from material and structural level was carried out. The former developed both molded specimens cores extracted in-situ constructed in Barcelona, Spain. results lead confirm that RA resulted satisfactorily manufacturing performance, since no affectations design variables (i.e., compressive flexural tensile strengths) were detected. Likewise, derived full-scale test evidenced residual loads slabs tested significantly higher than those calculated based prismatic core samples. main outcome research might be a suitable typology presented sufficient post-cracking capacity -due incorporation fibers- avoiding fragile failures. These conclusions could extended other countries where similar restrictive regulations standards are present, regarding FRC applications. • New cement consisting self compacting made with recycled aggregates fibers. Full-scale tests obtained manufacture pouring SRF-SCC-RA concretes walls, which full scale tests. direction impacts final disposition fibers wall; longer are, greater proportion remaining vertical direction.
