Análise das características físicas e propriedades mecânicas de argamassa com inserção de resíduos de madeira

Abstract: RESUMO A madeira, além de ser um material renovável, possui diversas propriedades que a torna muito atraente frente a outros materiais, dentre as quais, destaca-se as boas características de isolamento térmico. Tendo em vista que a construção civil é um setor com um elevado consumo de recursos naturais, qualquer ação proposta para diminuir impactos da construção civil sobre o meio ambiente contribui para o desenvolvimento sustentável. Este trabalho consiste em substituir o agregado miúdo por resíduo de madeira… Show more

“…The highest ratio (w/c) observed was 1.2 and the lowest was 0.35 (Andrade et al, 2018). According to Cipriano et al, (2021) and Silva et al, (2021) the increase in the ratio (w/c) is due to the need to maintain the workability of the material, and this fact may be attributed to the greater absorption of water from the recycled aggregates, which implies the migration of water to the aggregates, reducing the amount of water that contributes to the workability of the concrete. One way to give concrete with recycled aggregate greater workability, keeping the ratio (w/c) constant and equal to that of conventional concrete, is through the use of superplasticizing additives.…”
