Summary: The growth of civil construction and cement industry in the world has promoted sustainable cements development with the aim of decrease CO2 emission, generated during Portland Cement’s production. Another current challenge is the sustainable use of iron mining wastes, which are usually stored on piles and dams but should have a better destiny. Therefore, an alternative to alleviate these problems is to produce geopolymer using mining wastes as aggregates. The purpose of the study was comparing the effect of adding mining wastes as aggregates in geopolymers and evaluate their compressive strength. The results indicated that both waste and tailings were satisfactory alternatives in sustainable cement’s production, reaching strengths of 46 MPa and 53 MPa, respectively, 28 days after molding and cured at room temperature.

Outro desafio atual é o uso sustentável de resíduos de mineração, que poderiam ter destinos melhores que as pilhas e barragens. Nesse contexto, uma alternativa para amenizar esses problemas é a produção de geopolímeros utilizando resíduos de mineração como agregados. O objetivo desse trabalho foi comparar o efeito da adição de resíduos de mineração como agregados em geopolímeros e avaliar a resistência à compressão dos mesmos. Os resultados indicaram que tanto o estéril como o rejeito são alternativas satisfatórias na produção de cimentos sustentáveis, atingindo resistências de 46 MPa e 53 MPa, respectivamente, 28 dias após moldagem e curados em temperatura ambiente.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2022-12-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/12483HOLOS; v. 8 (2022)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/12483/3678Copyright (c) 2022 HOLOShttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMelo, Eduardo Lucas ProcópioFigueiredo, Ricardo Augusto MartinsMazzinghy, Douglas Batista2023-04-13T03:25:08Zoai:holos.ifrn.edu.br:article/12483Revistahttp://www2.ifrn.edu.br/ojs/index.php/HOLOSPUBhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/oaiholos@ifrn.edu.br||jyp.leite@ifrn.edu.br||propi@ifrn.edu.br1807-16001518-1634opendoar:2023-04-13T03:25:08Holos - Instituto Federal do Rio Grande do Norte (IFRN)false
