Resumo: | This article aims to determine the Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) in concrete through the replacement of Portland cement (PC) by high levels of limestone filer (LF) and fly ash (FA), in contents of 50% to 80%, with the purpose of reducing the CO2 emanations in the PC manufacture. LCA and LCC were applied with the intention of assessing the sustainability of the studied concretes based on environmental impacts and cost. The study showed that, due to the increase in the proportion of LF in the mixtures, the environmental impact is reduced due to the reduction in the use of PC. The behavior was observed in the totality of the studied environmental indexes, demonstrating the close relationship between the proportion of PC and the pollution of the environment, confirming, thus, the efficiency in the use of high contents of LF. The results showed the feasibility of concrete with high LF contents, from a technical-environmental point of view, considering that the achieved results pointed, unequivocally, to the excellent environmental performance of the mixtures. |

Foi aplicado a ACV e o CCV com a intenção de aferir a sustentabilidade dos concretos estudados com base nos impactos ambientais e no custo. O estudo demonstrou que, por ocasião da elevação da proporção de FC nas misturas, o impacto ambiental é reduzido devido a minoração da utilização de CP. O comportamento foi observado na totalidade dos índices ambientais estudados demonstrando a estreita relação entre a proporção de CP e a poluição do meio ambiente, chancelando, assim, a eficácia na utilização de elevados teores de FC. Os resultados mostraram a exequibilidade de concretos com elevados teores de FC, do ponto de vista técnico-ambiental, considerando que os resultados alcançados apontaram, de maneira inequívoca, para a excelente performance ambiental das misturas.UFSC - Federal University of Santa Catarina2022-05-312023-05-29T21:31:49Z2023-05-29T21:31:49Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/518710.29183/2447-3073.MIX2022.v8.n3.130-141https://repositorio.ufsc.br/handle/123456789/246690Mix Sustentável; Vol. 8 No. 3 (2022): Mix Sustentável (regular); 130-141MIX Sustentável; v. 8 n. 3 (2022): Mix Sustentável (regular); 130-1412447-30732447-0899reponame:Repositório Institucional da UFSCinstname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/5187/4027Copyright (c) 2022 Gustavo de Aguiar Isaia, Silvane Santos Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessIsaia, Gustavo de AguiarSilva, Silvane Santos2023-05-29T21:31:49Zoai:repositorio.ufsc.br:123456789/246690Repositório InstitucionalPUBhttp://150.162.242.35/oai/requestopendoar:23732023-05-29T21:31:49Repositório Institucional da UFSC - Universidade Federal de Santa Catarina (UFSC)false |
