Potential use of the lower cretaceous clay (Kef area, Northwestern Tunisia) as raw material to supply ceramic industry

Geotechnical and thermal tests have shown acceptable values of drying shrinkage (3%), firing shrinkage (10%), water absorption (8.9-15.9%) and a very high mechanical bending strength (17-20 MPa) indicating non-refractory clays. Those results further confirmed the potential application of the Albian clays from Slata site in ceramics.
