“…Their results highlighted the maximum value of α-coefficient of 0.93 (at 1500-1600 Hz) for the formulation with 5% added rubber. Wang and Du [63] found a The ability to sustain impact loads is a key requirement in the fabrication of paving elements for parking areas. Improving the toughness and the strain performance of blocks means enhancing their resistance to cracking induced by frequent wheel impacts, extending the service-life of the paving member [59].…”

“…Their results highlighted the maximum value of α-coefficient of 0.93 (at 1500-1600 Hz) for the formulation with 5% added rubber. Wang and Du [63] found a maximum α-value of 0.40 (at 1000 Hz) incorporating recycled rubber with particle size of 5-10 mm size, in replacement rate of 30%. Corredor-Bedoya et al [64] investigated the sound absorption performance of rubberized mortars containing 10%, 15%, and 25% (in mass) of rubber particles with 75-500 µm size distribution range.…”

The use of waste materials as alternative aggregates in cementitious mixtures is one of the most investigated practices to enhance eco-sustainability in the civil and construction sectors. For specific applications, these secondary raw materials can ensure adequate technological performance, minimizing the exploitation of natural resources and encouraging the circular disposal of industrial or municipal waste. Aiming to design and develop lightweight paving blocks for pedestrian or very light-traffic purposes (parking area, garage, sidewalk, or sports surfaces), this paper presents the material characterization of rubberized cement mortars using ground waste tire rubber (0–1 mm rubber powder and 1–3 mm rubber granules) to totally replace the mineral aggregates. Considering recommended requirements for concrete paving members in terms of mechanical strength, water drainage performance, acoustic attenuation, and dynamic and energy absorption behavior, a comprehensive laboratory testing is proposed for five different formulations varying the sand-rubber replacement level and the proportion ratio between the two rubber fractions. Tests highlighted positive and promising results to convert laboratory samples into pre-cast members. The “hot” finding of the work was to prove the feasibility of obtaining totally rubberized mortars (0 v/v% of sand) with suitable engineering performance and enhanced eco-friendly features.

“…Por lo tanto, sugirieron que la mayor absorción acústica del concreto recubierto de caucho se debe al aumento de los huecos de aire en el concreto (Mushunje, Otieno, & Ballim, 2018). (Wang & Du, 2020), consideraron el tamaño de partícula, la composición y la tasa de sustitución del material de caucho; se compararon y analizaron el rendimiento físico, el rendimiento térmico y el rendimiento acústico del concreto normal, el concreto de agregado reciclado y el concreto de caucho granulado reciclado RCC. Se compararon los principales índices de diferentes concretos, incluyendo densidad aparente, porosidad, coeficiente de transferencia de calor, resistencia térmica, coeficiente de absorción acústica y coeficiente de reducción de ruido.…”

Los avances en la tecnología del concreto conducen a la búsqueda de materiales alternativos que brinden mejoras en las propiedades del concreto y al mismo tiempo colaboren con reducir la contaminación del medio ambiente. En este artículo se revisará las investigaciones publicadas en revistas científicas indexadas en la base de datos Scopus y SciencieDirect, que tienen como objetivo estudiar el uso del caucho de neumáticos triturados para la producción de concretos en general. Se discutirá las metodologías y técnicas de trituración de las partículas de los neumáticos, así como también se destacará los avances realizados con la incorporación de material en el concreto, centrándose en las propiedades del concreto modificado con caucho de neumáticos. En conclusión, se discutirán las recomendaciones para las futuras investigaciones y la aplicación del caucho de neumático en el concreto.

“…In the past, ELTs have been considered as source material for artificial reefs, but this option was rejected due to the destruction of marine life as a result of tires decomposition [ 5 ]. Alternatively, ELTs may find utilization at erosion control; mine stabilization; in the production of asphalt; filler in cement composites by using rubber crumb produced by tire crushing; or alternatively reclaiming and devulcanization [ 6 , 7 , 8 ]. In this regard, ELTs have attracted significant attention of several research teams considering its beneficial properties such as endurance, thermal stability, chemical resistance, and mechanical parameters [ 9 ].…”

Environmental Consequences of Rubber Crumb Application: Soil and Water Pollution

et al. 2022

End-of-life tires are utilized for various purposes, including sports pitches and playground surfaces. However, several substances used at the manufacture of tires can be a source of concerns related to human health or environment’s adverse effects. In this context, it is necessary to map whether this approach has the desired effect in a broader relation. While the negative effects on human health were investigated thoroughly and legislation is currently being revisited, the impact on aquatic or soil organisms has not been sufficiently studied. The present study deals with the exposure of freshwater and soil organisms to rubber crumb using the analysis of heavy metal and polycyclic aromatic hydrocarbon concentrations. The obtained results refer to substantial concerns related to freshwater contamination specifically, since the increased concentrations of zinc (7 mg·L−1) and polycyclic aromatic hydrocarbons (58 mg·kg−1) inhibit the growth of freshwater organisms, Desmodesmus subspicatus, and Lemna minor in particular. The performed test with soil organisms points to substantial concerns associated with the mortality of earthworms as well. The acquired knowledge can be perceived as a roadmap to a consistent approach in the implementation of the circular economy, which brings with it a number of so far insufficiently described problems.
