description Comfort and habitability are requirements for housing quality, affected by underfloor system. Thus, this study aims to design lightweight concrete slabs underfloor with the use of ethylene vinyl acetate (EVA) aggregates, with two grain sizes of conventional aggregates replaced with EVA. The experimental counted on four unit mixes, varying the ratio between EVA coarse and fine aggregates and natural aggregates. The underfloor plates were molded with thickness of 3, 5 and 7 centimeters, and 3cm plus 1cm of conventional coating. Slabs were submitted to specific mass and standardized impact sound pressure level tests. Results showed a correlation between specific masses and impact sound values, being that 7cm thickness slabs with smaller specific mass, with total aggregate replacement, presented noise intensity reductions of 17dB in comparison to same thickness slabs with natural sand and smaller content of EVA coarse aggregate; and a 28dB reduction in relation to the slab without underfloor.

Así, este estudio objetiva diseñar losas de hormigón ligero con el uso de etileno-acetato de vinilo (EVA) como agregados en los contrapisos, sustituyendo agregados naturales El programa experimental está compuesto de cuatro mezclas, en que se modifica la relación entre los agregados grandes e pequeños de EVA y los naturales. Las losas de contrapiso tienen espesuras 3, 5 y 7 cm, la losa de 3 cm tuvo 1 cm adicional, con argamasa, simulando el acabamiento. Fueron realizados ensayos de masa específica y nivel de presión de sonido de impacto. Los resultados mostraron que a losa con 7cm y menor peso específico, presentó reducción de ruido de 17 dB, en comparación con aquellas de la misma espesura, con agregados naturales y menor contenido de EVA; y de 28 dB en relación a la losa de referencia.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
