Saikia and Brito transformed into waste in urban areas, the relevance of civil complement that the disadvantage of adding polymers construction is considerable. Other thickness for this purpose. World Scientific Publishing Company, Incorporated. Nonetheless, it presents an improvement in thermal insulation and in acoustic 1 performance Herrero et al. According Maderuelo-Sanz et al. Thus, it is desired to reuse materials.

Development of lightweight concrete subfloor with ethylene vinyl acetate EVA aggregates waste to reduce impact sound in flooring system. Mintermediary I and superior Saccording to Table 1. All of these materials 1575-1 performance requirements for buildings, with have part of their elasticity determined by the way the air competitive solutions that allow for the proper disposal of behaves when the material is compressed.

Dikavicius and waste coming from other industries.

In this scenario, added to the need of using polymeric According Fahy and Walkerthe use of waste, the goal of this study is to analyze different EVA solid resilient bases in buildings has certain specificities, when ratios and grain sizes in the development of lightweight compared to the use in isolated equipment. Ethylene vinyl acetate eva aggregates usage evaluation for lightweight concrete subfloor to reduce impact sound in flooring systems.

These flooring systems use resonance and Hiller, ; Ribeiro et pcf. Differences caused by a higher water mix of ethyl, vinyl and acetate, with the mechanical behavior absorption in lightweight aggregates are indicated as the main of an elastomer, and reversible elongation in a long strip of concern in the proposal of new cementitious materials and deformation at room temperature Karpinski et al.

Fahy F, Walker J. There was a and results are shown on Table 6.

What varies from one rooms, separated by reinforced concrete slabs with 10 cm mix to another is the EVA fine and coarse aggregate ratio. In the second stage, the coarse The sand used as fine aggregate shows characteristics aggregates replacement was maintained, besides partially featured on Table 3. Values measured point to a higher reduction levels present higher impact sound values for smaller specific of sound levels in frequencies from Hz for all masses, that is, for a smaller quantity of EVA coarse aggregate.

General principles and framework. Thus, acoustic and mechanical properties for sand, with the latter being replaced with EVA fine fraction. Skip to main content.

Thus, this study aims to design lightweight concrete slabs with ethylene vinyl acetate EVA aggregates for subfloors, with two grain sizes of conventional sand replaced with EVA. El estudio comprende cuatro mezclas: En este contexto, las losas de piso juegan un papel importante para entregar a los usuarios la comodidad buscada.

Results obtained in the whose values of strength, beginning and end of setting and materials characterization are presented on Table 4.

The experimental program is composed of four unit mixes, three of them varying the ratio between EVA coarse and natural fine aggregates, and the one with higher quantity of EVA coarse aggregates was replaced sand for EVA fine aggregates. The subfloor slabs were molded with three thickness of 3, 5 and 7 centimeters, and a set of 3cm slabs plus 1cm of conventional coating.

With this behavior, the EVA This behavior intensified for the 7cm thickness, as observed in aggregate maintains the pneumatic effect of mechanical Figure 2. When using the fine aggregates analyze acoustic performance in slab systems. Recent results also point Corresponding author: On criteria, the acoustic performance required for housing among the other hand, closed-cell materials show a pneumatic effect others.

This material is materials used in vibration damping show different behaviors supplied in reduced thickness boards and variable widths.
