Zusammenfassung: | The regions with lots of shoe production suffer environmental impacts from waste generation during manufacturing of insoles and outsoles. Research conducted in Brazil has demonstrated the technical feasibility to recycle these wastes, especially Ethylene Vinyl Acetate (EVA), as lightweight aggregate, in the production of non-structural cement blocks. This article presents an evaluation of thermal performance with measurements of temperature variation in mini walls (1 m super(2)) built with different materials, including various kinds of EVA block and ceramic bricks. Tests have shown efficient thermal performance for masonry blocks with EVA. These results and supplementary estimates contribute to add value to the EVA block, considering that there are good expectations that the component, with the new geometry proposed, can contribute to the energy efficiency of buildings, highlighting its suitability to most Brazilian bioclimatic regions.Original Abstract: Las regiones con una gran produccion de calzado sufren impactos ambientales derivados de la generacion de residuos durante la produccion de plantillas y suelas. Investigaciones realizadas en Brasil han demostrado la viabilidad tecnica para el reciclaje de estos residuos, especialmente el Etileno Vinil Acetato (EVA), como agregado ligero en la fabricacion de bloques de hormigon no estructurales. Este trabajo presenta una evaluacion del rendimiento termico, con mediciones de la variacion de la temperatura en pequenas paredes (1 m super(2)) construidas con diversos materiales, incluyendo algunos tipos de bloques EVA y ladrillos de ceramica. Las pruebas demostraron actuaciones termicas eficientes para las muestras con bloques EVA. Estos resultados y calculos adicionales contribuyen con un aporte de valor anadido al bloque EVA, considerando que existen buenas expectatives del componente, con una nueva propuesta de geometria, pudiendo contribuir a la eficiencia energetica de edificios, especialmente por su |
