Resumo: | Magnetite consists of a mineral with excellent magnetic and mechanical properties, being present in iron extraction tailings, which are available worldwide in millions of tons deposited in landfills. In relation to variety of the material characteristics, according to specificities of the extraction deposit and processing and reprocessing operations, for its technological application it´s fundamental to perform waste characterization. The most promising forms of magnetite tailings reuse refer to its application in asphalt mixtures and concrete. In this context, this work approaches the main techniques for the technological characterization of magnetite tailings and their contributions, as well as results of studies for incorporation of mineral byproduct into asphalt and concrete. It has been identified that techniques used analyze the tailings and/or composite asphalt material and concrete considering the physical, chemical, mineralogical and thermodynamic properties. The magnetite tail as a partial and integral substituent of the filler material has been found to improve the corrosion resistance and cracking of the asphalt mixtures. In addition, the use of magnetite powder, extracted from waste, improves stiffness and elastic response, as well as promotes microcracks cure of bituminous mixture. Incorporation of powdered mineral waste in the concrete resulted in improvements in the workability and strength of the material. The information in this review provides an overview of the characterization techniques and recycling prospects of magnetite tailings in civil construction. |

Ao considerar a variabilidade das características deste material, conforme especificidades da jazida de extração e das operações de processamento e reprocessamento, para a sua aplicação tecnológica é fundamental realizar a caracterização do resíduo. As mais promissoras formas de reaproveitamento do rejeito de magnetita referem-se a sua aplicação em asfalto e em concreto. Neste contexto, este trabalho aborda as principais técnicas de caracterização tecnológica de rejeitos de magnetita e suas contribuições, bem como resultados de estudos da incorporação do subproduto mineral em misturas betuminosas e concreto. Identificou-se que as técnicas utilizadas analisam os rejeitos e/ou material asfáltico compósito e betão considerando as propriedades físicas, químicas, mineralógicas e termodinâmicas. Verificou-se que o rejeito de magnetita, como substituinte parcial e integral do material de enchimento, melhorou a resistência à corrosão e às rachaduras das misturas asfálticas. Além disso, o uso de pó de magnetita, extraído do resíduo, melhorou a rigidez e a resposta elástica, bem como promoveu a cura de microfissuras da mistura betuminosa. A incorporação de resíduos do mineral em pó no concreto resultou em melhorias na trabalhabilidade e resistência do material. As informações desta revisão oferecem um panorama das técnicas de caracterização e das perspectivas de reciclagem dos rejeitos de magnetita no setor da construção civil.Zeppelini Publishers2019-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/51210.5327/Z2176-947820190512Revista Brasileira de Ciências Ambientais (Online); n. 54 (2019): RBCIAMB - ISSN 2176-9478 - Dezembro; 69-89Brazilian Journal of Environmental Sciences (Online); No. 54 (2019): RBCIAMB - ISSN 2176-9478 - December; 69-892176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESporhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/512/502Copyright (c) 2019 Revista Brasileira de Ciências Ambientais (Online)info:eu-repo/semantics/openAccessFerrazzo, Suéllen TonattoBragagnolo, LucimaraKorf, Eduardo Pavan2022-03-25T22:07:48Zoai:ojs.www.rbciamb.com.br:article/512Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2022-03-25T22:07:48Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false |
