Hazardous bauxite residue, blast furnace slag, and foundry sand application as the main components for environmentally friendly red ceramics production

In the presented research were used residues of aluminum and iron production. Bauxite residue, which is also called bauxite tailings or red mud, and blast furnace slag are the key wastes of metallurgical industry. There was also used foundry sand, which is a residue of casting process. These three c...

Nesta pesquisa foram utilizados resíduos da produção de alumínio e ferro. Resíduo de bauxita, que também é chamado de rejeitos de bauxita ou lama vermelha, e escória siderúrgica são os principais resíduos da indústria metalúrgica. Também foi utilizada areia de fundição, que é um resíduo do processo de fundição. Estes três componentes foram utilizados em conjunto para desenvolver material cerâmico de construção. A idéia principal era usar apenas resíduos industriais, sem materiais naturais tradicionais. Os residuos de vidro e as cinzas de madeira foram adicionados às composições para deminuir o ponto de fusão das amostras. Na pesquisa, 24 composições foram queimadas a 800-1225°C e suas propriedades foram estudadas. As características mecânicas das amostras foram analisadas através do teste de resistência à flexão, medindo-se a absorção de água, densidade e retração linear. As propriedades físico-quimicas foram estudadas por XRF, XRD, AAS, SEM, EDS, LAMMA, mapeamento, DTA e TGA. O principal motivo para os resultados elevados de resistência à flexão (19,78 MPa) das amostras foi identificado como o desenvolvimento de novas formações amorfas. Como resultado da pesquisa, algumas composições foram sugeridas para a produção específica de materiais de construção. Composições contendo lama vermelha (40- 100%), escória siderúrgica (0-50%), areia de fundição (0-50%), resíduo de vidro (0-20%) e cinzas de madeira (0-20%), atenderam normas e regulamentos brasileiros para materiais de construção, podem substituir materiais cerâmicos tradicionais, que envolvem a enorme exploração de recursos naturais. 2017-12-28T14:49:42Z 2017-12-28T14:49:42Z 2017-03-17 doctoralThesis ALEKSEEV, Kirill.
