The Saharan regions of Algeria are characterized by a hot and dry climate. The most used cement such as theconcrete or the mortar blocks have bad thermal However, these regions have several local clay, dune sand and some which are formerly proved their thermal efficiency. The price of construction used therefore depends on the international market constantly destabilized by theeconomic crisis coupled with the energy crisis in recent times. To produce a framework of life at a lower cost, it is important, therefore, to circumvent the influence of the cost of energy by upgrading the local of construction. In order to improve thermal performances in Saharan building this study was lanced. The aim of this research isthen to some bricks using three local namely the clay, sand dune and the fibers of date palm. The percentage of sand and fibers varies from 0% to 40% and 0% to 3% by mass respectively. A sand dune of Ain El Beida of Ouargla of Algeria was used. Clay was extracted from Beldet Amer of Touggourt Ouargla Algérie. The fibers used in this study were vegetable fibers from date palm of Ouargla Algeria. The results showed that increasing in the mass fraction of sand and of fiber were beneficial for improving thermal properties. As function of increasing the percentage of sand dune and fibers there were: A decrease in: thermal effusivity and and there were an increase in the thermal resistance.
