Abstract AR
إن هذه الدراسة تتمحور حول تحاليل معدنية, و جيوكيميائية, و فيزيائية, و جيوتقنية لعينات طينية أخذت من جبل الوسط بالشمال الغربي للبلاد التونسية.
و الهدف من ذلك هو تقييم صلاحية الطين لصناعة الخزف. و قد بينت هذه الدراسة أن هذه العينات غنية بالألمنيوم و الرمال, و يمثل معدن "إليت" illite أكثر من 90% إضافة إلى "كاوولينيت" kaolinite و خليط من "إليت / سمكتيت" illite/kaolinite mixed layers و لا يحتوي الطين على الجبس و "السمكتيت" smectite. و هذه العينات الطينية سهلة التجفيف لأن درجة التقلص عند التجفيف, تفوق 3.4%, و كذلك سهلة التسخين (1.25 - 2.32% درجة التقلص عند التسخين). و يتميز الطين بلدانة منخفضة حيث لا تفوق 18%.
و تعتبر درجة التمطط منحصرة أيضا.
و يمكن - بحسب هذه المعطيات - استعمال الطين في صناعة الخزف.
Abstract EN
This study focuses on the mineralogical, geochemical, physical, and geotechnical tests carried out on Valangenian–Hauterivian clays, collected from Djebel Oust in North West Tunisia.
The object of this study was to evaluate the potential of these clays to manufacture traditional ceramic products. The study has proved that these clays are aluminous and siliceous.
It has been shown that the clays are characterized by the presence of clay minerals such as illite (up to 90 %), kaolinite, I / Sm mixed layers, and the absence of gypsum and smectite. These clays adapt to fast drying because their drying shrinkage does not exceed 3.4 %.
They have a low firing shrinkage and plasticity with the less than 2.32 % and 18 %, respectively.
The firing expansion is also limited.
For these reasons, these clays can be used in the manufacturing of ceramic products.
