In this work high-density polyethylene residues were used as a component for the manufacture of self-compacting non-structural concrete. The proposal was to achieve a self-compacting concrete composed, entirely or in part, of polymer waste, maintaining its physical/mechanical properties and reducing costs for its production approaching the costs of manufacturing conventional concrete. The tests were performed by replacing the large aggregates for 25, 50, 75, and 100% polymer. The characterization of the concrete was carried out through fluidity tests, the slump flow test, achieving satisfactory results for a self-compacting concrete. The mechanical properties were performed by compression test and density was measured by the Archimedes method. The results show that the specific stiffness and strength of concretes whose large aggregates were replaced by polymer reached values even higher than conventional concretes. The microstructure and the connections between the phases were studied by MEV, EDS and CONFOCAL microscopy.
