This work presents the results of a study on the suitability of the clayey materials from Campos-RJ (Brazil) region for application in structural ceramic. The clayey materials, i.e. red clays available in this region, were selected so that their characteristics regarding chemical composition, rational analysis, X-ray diffraction, particle size analysis, thermal behavior, plasticity and as dried and fired properties could be studied. The results revealed that the studied samples are typically kaolinite based materials. In addition, it was found that almost all properties of these materials are led to the manufacture of structural ceramic. Mechanical strength test data resulted in Weibull distributions.
