Thermal and Acoustic Characterization of Recycled Ground Tyre Rubber and Aggregate Seismic Isolator

Year: 2025

Type: article

Abstract: Currently, large amounts of aggregate waste from the construction industry and ground tire rubber from the automotive sector are being generated. Enhancing and expanding recycling options for these materials is essential to support the transition toward a circular economy in both industries. This study proposes the use of recycled materials in the development of a seismic isolator designed for building partitions. As such, the new element must meet the performance requirements applicable to all materials used in building enclosures. Polyurethane is employed as a binder for the recycled components. The composite material is produced by combining polyurethane with varying proportions of recycled ground tire rubber and aggregates, expressed as a percentage of the polyurethane mass. The polyurethane is directly mixed with the recycled constituents. The resulting samples are subjected to thermal and acoustic testing to evaluate their suitability for partitions and enclosures in building construction in accordance with regulations. The results of the three tests indicate improvements in the measured properties, with the magnitude of enhancement depending on the ratio of ground tire rubber to aggregate. Overall, the developed composite materials exhibit characteristics and behavior compatible with the intended application.
