This work is dedicated to the promotion of local materials, the main purpose is the evaluation of a red marl clay abundant in M'sila region. Hitherto used in the production of local pottery, it contains clay components, such as kaolinite and illite. After a thermal analysis, a calcination degree was defined and slow calcination was carried out in a fixed laboratory furnace during 5 hours. The calcined clay is mixed with clinker to produce new cement. It has been studied following standard tests - physical, chemical and mechanical properties - and compared with a Portland cement in the same laboratory.
The conclusion was beneficial, as it was found that 10% addition gives the best results, with a srength of 43MPa and 44MPa for portland cement.
