Influência do agregado reciclado na durabilidade do concreto armado frente a corrosão de armadura desencadeada por carbonatação acelerada

Abstract: A construção civil gera impactos ambientais devido a produção dos resíduos de construção e demolição (RCD). O principal objetivo desse artigo é estudar a durabilidade dos concretos produzidos com diferentes percentuais de agregado reciclado em sua matriz analisando seus comportamentos. Foram confeccionados corpos-de-prova (CP’s) prismáticos com dimensões (10 cm x 10 cm x 6 cm) contendo barras de aço com diâmetro Ø de 6 mm e, a partir disso, foram moldadas 4 famílias: sem (RCC) – referência, com 15%, 25% e 50% … Show more

“…Concrete durability is an essential issue, as it makes it possible to understanding a material's performance throughout a structure's lifetime (Kashani et al, 2017). Moreover, it can be affected by the action of external aggressive agents, such as chloride ions or carbon dioxide -CO2 (Shon et al, 2018;Nascimento et al, 2021). One of the principal problems related to the durability of reinforced concrete is the corrosion of steel bars leading to the degradation or loss of the structural properties of the material.…”

“…The durability of concrete is an essential issue, as it allows understanding the performance of the material during the entire life of a structure (Kashani et al, 2017). In addition, it can be affected by the action of external aggressive agents, such as chloride ions and (CO2) -carbon dioxide (Nascimento et al, 2021). According to Azevedo et al, (2020) civil construction, despite having great importance in the economy, is the largest consumer in the world of natural raw materials among industrial sectors.…”
