Resumo: | Canga is a residual product resistant to mechanical weathering and practically inert chemical weather. The wide occurrence of this material in the region of Ouro Preto viability their use on behalf of the community and encourage studies about their physical and chemical properties. In this context, this pioneering research supporting the use of canga in the ornamental rock sector focus as dimension stone. The samples collected in geological site of Ouro Preto was characterized using x-ray diffraction, density and porosity determinations, Rockwell hardness test, Schmidt rebound hammer test and chemical analysis. The Schmidt rebound hammer tests were very efficient to detect internal imperfections, which was proven by the test of porosity. In addition, the fact of this test be non - destructive with easy realization makes their use viable, because there is no material lost. The performance of material compared with quartzite, usually used as dimension stone, was proved for this purpose. Its properties even suggest the application in other sectors such as ceramics and construction. |

A grande ocorrência desse material na região de Ouro Preto e a viabilização do seu uso em prol da comunidade incentivam o seu estudo e desperta o interesse em conhecer suas propriedades físicas e químicas. Nesse contexto, surge essa pesquisa pioneira fundamentando a utilização da Canga no setor de rochas ornamentais com enfoque na arte da Cantaria. As amostras coletadas no sítio geológico da região em estudo foram caracterizadas utilizando difratometria de raios-X, ensaios de massa específica e porosidade, determinação de dureza Rockwell e ensaios não destrutivos com o esclerômetro Schmidt. Os testes com o esclerômetro mostraram-se muito eficientes para detectar imperfeições internas na peça, o que foi comprovado pelo teste de porosidade. Além disso, o fato desse teste ser não destrutivo e de fácil realização torna a sua utilização viável, não ocorrendo perda de material. O desempenho do material no decorrer do estudo encoraja o seu prosseguimento, visto que, mediante correlação realizada com quartzito, usualmente utilizado como rocha ornamental, foi comprovada a configuração da canga para esta finalidade. Suas propriedades ainda sugerem a aplicação em outros setores como de cerâmica e construção civil.Autorização concedida ao Repositório Institucional da UFOP pela Tecnologia em Metalurgia Materiais e Mineração em 22/11/2013 para depositar uma cópia eletrônica dos artigos publicados por esse periódico em que ao menos um dos autores é aluno ou professor da UFOP.info:eu-repo/semantics/openAccessCharacterizationCaracterizaçãoUse of canga as dimension stone.Uso da canga como rocha ornamental.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleengreponame:Repositório Institucional da UFOPinstname:Universidade Federal de Ouro Preto (UFOP)instacron:UFOPLICENSElicense.txtlicense.txttext/plain; charset=utf-8924http://www.repositorio.ufop.br/bitstream/123456789/10256/2/license.txt62604f8d955274beb56c80ce1ee5dcaeMD52ORIGINALARTIGO_UseCangaDimension.pdfARTIGO_UseCangaDimension.pdfapplication/pdf822245http://www.repositorio.ufop.br/bitstream/123456789/10256/1/ARTIGO_UseCangaDimension.pdfc33a5a55a61b37aae2d0b26d9bd3845dMD51123456789/102562018-09-26 12:30:43.826oai:localhost:123456789/10256RGVjbGFyYcOnw6NvIGRlIGRpc3RyaWJ1acOnw6NvIG7Do28tZXhjbHVzaXZhCgpPIHJlZmVyaWRvIGF1dG9yOgoKYSlEZWNsYXJhIHF1ZSBvIGRvY3VtZW50byBlbnRyZWd1ZSDDqSBzZXUgdHJhYmFsaG8gb3JpZ2luYWwgZSBxdWUgZGV0w6ltIG8gZGlyZWl0byBkZSBjb25jZWRlciBvcyBkaXJlaXRvcyBjb250aWRvcyBuZXN0YSBsaWNlbsOnYS4gRGVjbGFyYSB0YW1iw6ltIHF1ZSBhIGVudHJlZ2EgZG8gZG9jdW1lbnRvIG7Do28gaW5mcmluZ2UsIHRhbnRvIHF1YW50byBsaGUgw6kgcG9zc8OtdmVsIHNhYmVyLCBvcyBkaXJlaXRvcyBkZSBxdWFscXVlciBwZXNzb2Egb3UgZW50aWRhZGUuCgpiKVNlIG8gZG9jdW1lbnRvIGVudHJlZ3VlIGNvbnTDqW0gbWF0ZXJpYWwgZG8gcXVhbCBuw6NvIGRldMOpbSBvcyBkaXJlaXRvcyBkZSBhdXRvciwgZGVjbGFyYSBxdWUgb2J0ZXZlIGF1dG9yaXphw6fDo28gZG8gZGV0ZW50b3IgZG9zIGRpcmVpdG9zIGRlIGF1dG9yIHBhcmEgY29uY2VkZXIgw6AgVW5pdmVyc2lkYWRlIEZlZGVyYWwgZGUgT3VybyBQcmV0by9VRk9QIG9zIGRpcmVpdG9zIHJlcXVlcmlkb3MgcG9yIGVzdGEgbGljZW7Dp2EgZSBxdWUgZXNzZSBtYXRlcmlhbCwgY3Vqb3MgZGlyZWl0b3Mgc8OjbyBkZSB0ZXJjZWlyb3MsIGVzdMOhIGNsYXJhbWVudGUgaWRlbnRpZmljYWRvIGUgcmVjb25oZWNpZG8gbm8gdGV4dG8gb3UgY29udGXDumRvcyBkbyBkb2N1bWVudG8gZW50cmVndWUuCgpjKVNlIG8gZG9jdW1lbnRvIGVudHJlZ3VlIMOpIGJhc2VhZG8gZW0gdHJhYmFsaG8gZmluYW5jaWFkbyBvdSBhcG9pYWRvIHBvciBvdXRyYSBpbnN0aXR1acOnw6NvIHF1ZSBuw6NvIGEgVUZPUCwgZGVjbGFyYSBxdWUgY3VtcHJpdSBxdWFpc3F1ZXIgb2JyaWdhw6fDtWVzIGV4aWdpZGFzIHBlbG8gY29udHJhdG8gb3UgYWNvcmRvLgoKRepositório InstitucionalPUBhttp://www.repositorio.ufop.br/oai/requestrepositorio@ufop.edu.bropendoar:32332018-09-26T16:30:43Repositório Institucional da UFOP - Universidade Federal de Ouro Preto (UFOP)false |
