STUDY ON PERMEABILITY, SOUND INSULATION FOR LIGHT WEIGHT CONCRETE MIXTURE WITH INDUSTRIAL EVA WASTE

This paper aims to study the permeability and evaluate the concrete structure ,sound insulation property and quality control for proportional additions of EVA waste as constituent of lightweight concrete with different densities .This study also intended to present a proposed empirical formula to determine the sound insulation of concrete cubes by using UPV, Samples of various proportions (10%, 25%, 40%, 55%, and 70%) of EVA waste in the mix and a control sample,(0%) were cured in water tanks for 28days. The sound insulation of concrete area calculated according to a proposed empirical formula made in this work . It was found that permeability decrease with increase in replacement percentage of EVA waste compared with the normal conventional concrete, Results showed that using10% EVA gave the lowest permeability and the best performance, Results of sound insulation showed transmission losses increased with decreased the average weight per area unit for concrete mixtures. Accordingly it was concluded that there is an indirect relationships between the amount of the EVA in the mix and the sound insulation of the product. Same relation was noticed against compressive strength.
