Résumé: This study concerns the determination of the phase composition and physical properties as well as mechanical properties of fired products of two samples clays A1and A2,the most representative, taken from clay dominated formation in southern Tunisia. For temperatures up to 900°C, the products have high values of apparent porosity, which lead to low bulk density ceramics having low mechanical resistance. Above 900°C and up to 1200°C, the obtained products show the presence of mullite and cristobalite, the ceramics are dense and have high mechanical resistance, without deformation or defects. These clay materials may be used for the production of terracotta products and also for the formulation of low porosity ceramics. 2011-01-01T00:00:00Z
