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.en-USabertoCharacterizationCaracterizaçãoArtigo publicado em periodicoAutorização 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.
