Abstract

The Cretaceous clays of north-western Tunisia have been studied for their use in the traditional ceramic industry (bricks, tiles and pottery). Mineralogical, chemical, thermal analyses, technological proprieties and grain size distribution were carried out on clay samples collected from Jebel El Moura (BM section) and kef Lasfar-Oued El Jebs (MK section) in the locality of Mjez el Beb. The results showed that these clay minerals are represented mainly by kaolinite associated with illite and smectite. Quartz, calcite, feldspars and hematite were also detected as accessory minerals in the whole rock. The amount silica is convenient for the manufacture of ceramic products. So the prepared mixtures were made without admixture of any variety of silicate. The technology tests revealed that the modelled products had small shrinkage during drying and firing, and a high bending strength. For this reason, the clay mixtures were made without admixture of quartz or any other component. As a result, Mjez el Beb clays have high qualities necessary for the manufacture of tiles and ceramic bricks.
