Análise da fluência por compressão no isolamento ao ruído de impacto de placas cimentícias com resíduo de EVA

Abstract: Resumo Os ruídos de impacto nas edificações multipavimentos são reduzidos com a execução de piso flutuante, caracterizado pela inclusão de um material resiliente entre o contrapiso e a laje. Nesse estudo, buscou-se avaliar a influência da compressão desse material no desempenho acústico do sistema. Dois materiais resilientes foram comparados, um produzido em laboratório (placas cimentícias com resíduos EVA -PEVA1,8), e outro comercial (manta recicladas de resíduos PET - MantaPET). As medições visando relaciona… Show more

“…EVA possesses favorable characteristics, such as good processability, thermal stability, impact resistance, fatigue resistance, resilience, toughness, and flexibility [4][5][6]. As a result, numerous studies have been conducted to explore its potential as an aggregate in the civil construction sector, aiming to produce lightweight concretes with good acoustic and thermal performance [7][8][9].…”
