Resumo: Red mud is the main by-product from bauxite processing, known worldwide as the Bayer process. Its production is growing all over the world, with a highlight in Brazil, the states of Pará and Minas Gerais. However, due to the chemical characteristics of this waste, as well as the high amount that is generated, environmental agencies are increasingly demanding that the generating sources create methods for reusing this waste, in order to collaborate with the reverse logistics of this material. In this sense, several studies have been carried out aiming at the reuse of red mud for the production of new materials, among which the light aggregate stands out, which can be used in the civil construction sector, which is one of the largest consumer sources of this type of product. Based on this bias, the present study evaluated, based on a systematic literature review, the potential application of red mud in the manufacture of lightweight aggregates. Important data such as: chemical composition; density; granulometry; mechanical resistance; water absorption; sintering temperature and application in concrete were analyzed and compared with the relevant standards on the subject. The results are encouraging, proving that in all parameters analyzed, the recycled aggregates produced met the normative standards currently required, having a performance similar to that of conventional aggregates. Therefore, it was concluded that red mud has technical feasibility for the manufacture of light aggregates, confirming the potential of reverse tailings logistics for this purpose.

Su producción está aumentando en todo el mundo, con énfasis en Brasil, los estados de Pará y Minas Gerais. Sin embargo, debido a las características químicas de este relave, así como a la alta cantidad que se genera, los organismos ambientales han venido exigiendo cada vez más a las fuentes generadoras que creen métodos de reutilización de este relave, con el fin de colaborar con la logística inversa de este material. En este sentido, se han realizado varios estudios con el objetivo de reutilizar el lodo rojo para la producción de nuevos materiales, entre los que se destaca el árido ligero, que puede ser utilizado en el sector de la construcción civil, que es una de las mayores fuentes de consumo. de este tipo de material producto. En ese sesgo, el presente estudio evaluó, a partir de una revisión sistemática de la literatura, el potencial de aplicación de los lodos rojos en la fabricación de agregados livianos. Datos importantes como: composición química; densidad; granulometría; resistencia mecánica; absorción de agua; Se analizó la temperatura de sinterización y aplicación en el concreto y se comparó con las normas pertinentes sobre el tema. Los resultados son alentadores, demostrando que en todos los parámetros analizados, los áridos reciclados producidos cumplían con los estándares normativos exigidos actualmente, con un comportamiento similar al de los áridos convencionales. Se concluyó, por tanto, que el lodo rojo tiene factibilidad técnica para la fabricación de agregados ligeros, confirmando el potencial de la logística inversa de los relaves para este fin.A lama vermelha é o principal subproduto proveniente do beneficiamento da bauxita, conhecido mundialmente como processo Bayer. Sua produção é crescente em todo o mundo, tendo como destaque no Brasil, os estados do Pará e Minas Gerais. No entanto, devido às características químicas deste rejeito, bem como a alta quantidade que é gerada, os órgãos ambientais vêm exigindo cada vez mais que as fontes geradoras criem métodos de reutilização deste rejeito, a fim de colaborar com a logística reversa deste material. Nesse sentido, diversos estudos têm sido realizados visando o reaproveitamento da lama vermelha para a produção de novos materiais, dentre os quais se destaca o agregado leve, que pode ser empregado no setor da construção civil, que é uma das maiores fontes consumidoras deste tipo de produto. Neste viés, o presente estudo avaliou, a partir de uma revisão sistemática da literatura, o potencial de aplicação da lama vermelha na fabricação de agregados leves. Dados importantes como: composição química; densidade; granulometria; resistência mecânica; absorção de água; temperatura de sinterização e aplicação em concretos foram analisados e comparados com as normas pertinentes sobre o assunto. Os resultados são animadores, comprovando que em todos os parâmetros analisados os agregados reciclados produzidos atenderam aos padrões normativos exigidos atualmente, tendo desempenho semelhante aos de agregados convencionais. Concluiu-se, portanto, que a lama vermelha possui viabilidade técnica para fabricação de agregados leves, confirmando a potencialidade da logística reversa do rejeito para este fim.Research, Society and Development2022-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2762410.33448/rsd-v11i5.27624Research, Society and Development; Vol. 11 No. 5; e12211527624Research, Society and Development; Vol. 11 Núm. 5; e12211527624Research, Society and Development; v. 11 n. 5; e122115276242525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/27624/24390Copyright (c) 2022 Adiel José Passos da Cunha Júnior; Dênis Carlos Lima Costa; Alcebíades Negrão Macêdohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCunha Júnior, Adiel José Passos daCosta, Dênis Carlos Lima Macêdo, Alcebíades Negrão2022-04-17T18:18:56Zoai:ojs.pkp.sfu.ca:article/27624Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:45:17.651651Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
