Abstract(s)
A sustentabilidade ambiental é cada vez mais um tema discutido, a preocupação com o meio ambiente é crescente. Como reduzir o uso de matérias-primas e o que fazer com os resíduos provenientes da atividade humana? São questões que têm sido exploradas ao longo dos tempos.
O setor da construção civil tem-se focado na inserção de resíduos sólidos para a produção de betões, travando assim o crescente depósito de materiais em aterro. Esta prática amiga do ambiente dá nova vida a materiais como o vidro, cerâmicas e até mesmo resíduos provenientes de demolições.
A durabilidade das estruturas é também uma preocupação, associada à precoce degradação observadas nas estruturas. Nos últimos anos a Construção Civil tem se voltado para a extensão da vida útil das estruturas de betão, assim como medidas que permitam aumentar a durabilidade das mesmas.
Assim, este estudo debruçou-se sobre o comportamento mecânico e a durabilidade de betão contendo agregados reciclados de resíduos de vidro. Onde foram substituídos tanto agregados grossos como agregados finos. Deste modo, foram produzidos cinco tipos diferentes de betão, um betão de referência e os restantes com substituição de agregados finos e grossos, formando combinações: 50-50%, 50-100%, 100-50%, 100-100%.
Os resultados obtidos apresentam apenas pequenas discrepâncias, concluindo-se que é viável tecnicamente, o uso de agregados reciclados no betão de forma racional e em atenção as propriedades desejadas.
Environmental sustainability is increasingly a subject discussed, the concern with the environment is increasing. How to reduce the use of raw materials and what to do with the wastes from human activity? These matters have been explored throughout the ages. The construction sector has focused on inserting solid wastes for the production of concrete, stopping the increase of materials in landfill. This environmentally friendly practice gives new life to materials such as glass, ceramics and even waste from demolition. The durability of structures is also a concern, associated with the degradation observed in early structures. In recent years, Construction has been returned to the extension of the useful life of concrete structures, as well as measures to increase the durability of the same. Therefore, this study has on the mechanical behavior and durability of concrete containing recycled aggregates of glass waste. Where were replaced both aggregated as thick as thin aggregates. In this way, were produced five different types of concrete, a reference concrete and the others with thick and thin aggregates replacement, forming combinations: 50-50%, 50-100%, 100-50%, 100-100%. The results obtained show only minor discrepancies, concluding that it is technically reliable, the use of recycled aggregates in concrete in a rational way and note the desired properties.
