摘要：All the dams in the world are exposed to the phenomenon of sedimentation, which is observed largely in Algeria. The dredging is considered as a vital activity for the exploitation of the dams. However, the quantities of the sediments (mud) evacuated by the operations of dredging will lead to the pollution of the rural environment. The aim is to suggest some economic and competitive formulations and easy to put into practice which give us an opportunity to exploit these materials in the manufacturing of the common concrete by the partial substituting with cement (10, 20 and 30%) of the mud after calcination at 750 °C to make them active. Some tests were done on concrete in the fresh and hard state in order to know their features. The obtained results have confirmed the possibility to elaborate the concretes including the calcinated mud with doses reaching till 30%.The quality of these concretes at fresh state or hard state permits to reach the economical, ecological and technological aims.
