Impact Sound Insulation of Lightweight Concrete Floor with EVA Waste
This study presents an evaluation of acoustic performance of lightweight concrete with EVA waste to reduce impact noise on floors. Three types of concrete with three different mix proportions were evaluated and were made relationships between impact noise levels and results of water absorption, voids and density of the samples. The experimental study of noise impact followed the procedures of ISO 140. The results indicate that the lightweight concrete with EVA recycled aggregate can reduce impact noise levels by up to 15 dB and the highest percentage of coarse aggregate EVA does not entail a higher acoustic performance.
