This study is part of the valuation of local materials such as clay (earth) and alfa in the region of northern Morocco, with the aim of using them as building brick walls. These materials are abundant natural and renewable. Objective of this work is to study the thermal and mechanical behavior of a new material by mixing the Clay (chosen as linking) with different percentages of mass fiber alfa (0.5, 1, 2, 3, 4%, respectively) and to compare these results with those of material often used in the construction of individual houses in the rural area of Morocco (clay+straw). The results obtained, we will deduct that the incorporation of straw fibers can lower the thermal conductivity compared to fibers alfa which allows to have an energy economy of 2℅ to 7℅., In part against the fibers alfa can improve the mechanical behavior of material to clay base in comparison with the material (clay+ straw) (An increase of 8℅ to 17℅ for the tractive resistance by bending and 6℅ to 18℅ for the resistance to compression).
