Acoustic Performance of Resilient Materials Using Acrylic Polymer Emulsion Resin

Abstract

There have been frequent cases of civil complaints and disputes in relation to floor impact noises over the years. To solve these issues, a substantial amount of sound resilient material is installed between the concrete slab and the foamed concrete during construction. A new place-type resilient material is made from cement, silica powder, sodium sulfate, expanded-polystyrene, anhydrite, fly ash, and acrylic polymer emulsion resin. Its physical characteristics such as density, compressive strength, dynamic stiffness, and remanent strain are analyzed to assess the acoustic performance of the material. The experimental results showed the density and the dynamic stiffness of the proposed resilient material is increased with proportional to the use of cement and silica powder due to the high contents of the raw materials. The remanent strain, related to the serviceability of a structure, is found to be inversely proportional to the density and strength. The amount of reduction in the heavyweight impact noise is significant in a material with high density, high strength, and low remanent strain. Finally, specimen no. R4, having the reduction level of 3 dB for impact ball and 1 dB for bang machine in the single number quantity level, respectively, is the best product to obtain overall acoustic performance.

Recycled Expanded Polystyrene as Lightweight Aggregate for Environmentally Sustainable Cement Conglomerates

“…EPS resins are widespread polymers in the building/construction field and in civil engineering, usually available in sheet form, shapes or large blocks and used for floor insulation, closed cavity walls, roofs, etc., but also employed in road foundations, pavement construction, impact sound insulation, drainage, modular construction elements, lightweight conglomerates (concretes, mortars), etc. [28][29][30][31][32][33][34].…”

Evaluation of Mechanical Properties with the Use of EPS Polymer for the Preparation of Sustainable Composite Based on Concrete

“…The application and use of EPS styrofoam (expanded polystyrene), in addition to being technological, has a low environmental impact for the optimization of production processes and the reduction of by-products [13][14][15][16]. This polymer, EPS, is a fully recyclable material and widely used due to its cost-effectiveness, versatility and satisfactory performance characteristics in civil construction [15][16][17][18][19]. EPS is widely used in many applications (buildings, packaging) due to relevant characteristics such as thermal insulation, durability, lightness, resistance, shock absorption and processability allowing high performance and obtaining economical products [20][21][22][23].…”
