3. Thermo-mechanical analysis of mass concrete elements made of rubberized concrete
Resumo Neste estudo, foram avaliadas amostras de concreto massa com borracha (concreto emborrachado) para determinar se a adição de partículas de borracha aumentaria a resistência à fissuração devido a variações volumétricas de origem térmica, em comparação com um concreto de referência, sem borracha. Amostras dos concretos estudados foram inic

4. Concreto com borracha de recauchutagem de pneu para uso em pavimentação de baixo tráfego
RESUMO O aumento da demanda por veículos acarreta maior produção de novos pneus. No entanto, após o término de sua vida útil, eles se tornam um passivo ambiental de difícil descarte adequado, tanto pela demora em se decompor quanto por seu grande volume. Sua disposição inadequada causa grandes danos ao meio ambiente e favorece a proliferação de ve

5. The use of tire rubber in the production of high-performance concrete
Abstract The advances in concrete technology lead to the search for alternative materials that provide improvements in concrete properties while at the same time collaborating with sustainable practices in construction. In this study, the influence of the incorporation of waste tire rubber on the mechanical properties of high-performance concrete was discuss

6. Estrategia para la optimización de un compuesto de caucho con aceite de soja utilizando diseños de experimentos
ABSTRACT When a rubber component is made, is necessary to start from a “rubber compound” which may be composed of one or more polymers and various additives or fillers. The development of an elastomer mixture to produce a compound with a specific end-use is complicated in the field of rubber technology. Therefore, the successful development of a compound

7. Influence of SEBS-MA and SBS compatibilizers on properties and morphology of blends of polystyrene/rubber residue (SBRr) from the footwear industry
Abstract The reuse of rubber waste is very important today, both to reduce the harmful effects on the environment, and to reduce the cost of new material development. Considering that most of the studies reported in literature refer to the reuse of tire waste, this article aims to evaluate the influence of styrene-butadiene-styrene (SBS) and styrene-(ethylen

8. Blends of ground tire rubber devulcanized by microwaves/HDPE - Part B: influence of clay addition
AbstractThe main objective of this work is to study the influence of clay addition on dynamically revulcanized blends of Ground Tire Rubber (GTR)/High Density Polyethylene (HDPE). GTR was previously devulcanized in a system comprised of a conventional microwave oven adapted with a motorized stirring, with a fixed microwave power and at various exposure times

9. Blends of ground tire rubber devulcanized by microwaves/HDPE - Part A: influence of devulcanization process
Abstract The main objective of this work is the study of the influence of microwaves devulcanization of the elastomeric phase on dynamically revulcanized blends based on Ground Tire Rubber (GTR)/High Density Polyethylene (HDPE). The devulcanization of the GTR was performed in a system comprised of a conventional microwave oven adapted with a

10. Development and characterization of post-consumer rubber tire powder, high density polyethylene and ethylene-octene-1copolymer ternary mixtures
Scrap tires are considered a type of waste that litters landfills and the environment in general. Due to its chemically cross-linked structure, this material cannot be recycled by conventional processes because it does not melt. This work examined the production of polymeric composites using high density polyethylene (HDPE) filled with rubber tire powder (RT

11. Thermoplastic elastomers blends based on linear low density polyethylene, ethylene-1-octene copolymers and ground rubber tire
Blends of linear low density polyethylene (LLDPE) ethylene-1-octene copolymers (EOC), with different 1-octene (OC) content, and ground rubber tire (GRT) were prepared by melt mixing in a twin screw extruder. Five different compositions of LLDPE/EOC/GRT blends were processed in the extruder to evaluate the effect of EOC addition to the LLDPE/GRT blends. The a

12. Evaluation of the effect of the incorporation of rubber tire waste particles on the properties of PP, HIPS and PP/HIPS matrices
In recent years, the consumption of plastics has been increasing and as consequence, the waste generated has also increased. Rubber tire (RT) waste is another residue which causes significant problems to society. In view of the considerable amounts of RT waste generated, this study aimed to evaluate the influence of the incorporation of RT particles into pos
