Resumen

Currently, recycling materials is one of the solutions to combat pollution. This research reused EPS (expanded polystyrene) and PVC-U (rigid polyvinyl chloride) in mixtures to manufacture structural concrete blocks, analyzing their behavior in compressive strength. Substitution percentages of 10% and 20% were used, where EPS replaced the fine aggregate and PVC-U replaced the coarse aggregate. The results of physical properties (warping, absorption, suction, dimensional variability) complied with RNE E.070 (National Building Regulations-masonry) and NTP 399.602 (Peruvian Technical Standard-masonry units). The compressive strength of the block with EPS decreased by 14% and 21.63%, while that of the block with PVC-U decreased by 12.69% and 21.79%, but both values remained within the requirements of NTP 399.602.
