Análise do comportamento mecânico de concreto com agregado reciclado e adição de fibras de aço e de vidro AR

Abstract: RESUMO A extensa utilização do concreto no mundo provoca a geração de grandes quantidades de resíduos, vinculada a sua produção e utilização. Hoje, esse resíduo é subestimado, porém em alguns países o seu uso como agregado reciclado é permitido na produção de novos concretos. Estudos apontam que o agregado reciclado no concreto pode diminuir algumas das suas características mecânicas. Visando mitigar este problema, propõe-se o estudo do comportamento deste compósito com resíduos, adicionando fibras. O objetivo… Show more

“…Additionally, it highlights the potential of hybrid FRP laminates to enhance mechanical properties and increase resilience [42,43]. The investigation improves durability and corrosion resistance, encourages broader use of FRP materials in civil engineering, and contributes to advancing knowledge in the field [44].…”

“…The EDX results, which show that the amount of calcium hydrate in RSAC with 50% superplasticizer was less than that in RBAC with 50% superplasticizer, corroborate this conclusion (Figure 14(a) and (b)). The C-S-H content was reduced as a result of the rise in the superplasticizer ratio, which was caused by the decrease in silicate hydrate (S i ) and the increase in CH content [30]. The increase in porosity was made possible by the decrease in C-S-H.…”
