This work presents an experimental study concerning the characterization of a mortar in raw earth chosen as material of construction in which we have to strengthen him by fibers of vegetable (chopped straw), to improve these mechanical performances. In this respect, we preceded to develop composites in earth by a protocol traditional, with various percentages of straw fibers (1 %, 2 %, 3 %, 4 % and 5 %). The realized test tubes were also tested in axial close compression, what allowed to highlight the importance of the percentage of the addition on the mechanical behavior of the material. The results showed that the mortar of earth(ground) strengthened by vegetable fibers in 3 % possesses an improvement of its mechanical properties in the flexion.
