The objective of this paper is to characterize a mixture of clays in the area of Campos dos Goytacazes-RJ used in the fabrication of bricks. It makes possible to evaluate the possibility of application of this body in the production of others products with greater aggregate value, as roof tiles, wall and floor tiles. In this work were realized the following tests: chemical composition, differential thermal analysis(DTA), thermogravimetric analysis(TGA), particle size distribution analysis and determination of physical-mechanical properties in function of the temperature of it burns. The results demonstrated that the ceramic body studied is appropriate for the production of massive and walled bricks. However to manufacture roof tiles, floor and wall tiles it is necessary to manipulate the body formulation to obtain the of properties in agreement with technical norms in use.
