The construction materials usually used in the large Algerian Sahara are the concrete, cinder, mortar which represents poor thermal propretés which adversely effects on the energy consumption. The Great Sahara of our country is characterized by a hot and dry climate in summer, cold, and dry in the winter. In the concern of valuing materials, premises and contribute to the reduction of this consumption (loads), and to improve the thermal comfort in the buildings it is necessary to implement of materials particularly performing providing a good thermo mechanical cleanliness to. The purpose of this research is to make the study of these three major parties: - Study of thermal properties of hollow bricks industrial but where the holes in the bricks are filled by a mixture clay more dune sand - Study of the thermal and mechanical properties of the raw clay bricks plus dune sand where the percentage of sand and 0%; 10%; 20%; 30% and 40% these will be reinforced by palm fibers where the percentage and 0%; 1%; 2% and 3% by mass and the thermal and mechanical properties of the bricks in which the percentage of clay and 100%; 99%; 98%; 97% reinforced with palm fibers where the percentage and 0%; 1%; 2% and 3% by mass - Thermal study on prototypes of 1 m2 made of raw bricks The results showed that the increase in% of fiber is beneficial for the improvement of thermal properties with acceptable mechanical resistances. At 1400 we obtained a very remarkable temperature difference compared to the prototype control
