Reaproveitamento de resíduos de borracha de pneus em betões

Abstract

Estima-se que anualmente 1.000 milhões de pneus atingem o fim da sua vida útil e que no ano 2030 esse número atinja 5.000 milhões de pneus. Actualmente só uma pequena parte desses resíduos é reciclada, sendo que milhões de pneus são apenas amontoados, colocados em aterro ou enterrados. O presente artigo sintetiza o estado actual dos conhecimentos técnicos e científicos sobre o desempenho dos betões contendo resíduos de borracha de pneus. São objecto de análise a influência dos tratamentos dos resíduos de borracha, a dimensão das partículas da borracha e o volume de substituição de agregados por resíduos de borracha nas propriedades dos betões no estado fresco e endurecido.
