In recent years, the development of housing and infrastructure construction in Morocco has created a huge need for building materials and a growing shortage of traditional materials from quarries. From there, the idea of designing eco-building materials based on local materials that have proven their use for millennia, through remarkable heritage sites was born. The purpose of this work is to experimentally upgrade local materials that have long been used, whether in construction or other uses. These materials are made based on soil and static compaction method compared by manual method. We stabilized them with the addition of fibers of palm doum (at mass contents up to 2.5% with a pitch of 0.5% whose average lengths are 0.1cm, 1cm and 3cm) and/or of a binder (cement whose percentage contents are 0%-5%-10%-12% or the same for lime). The mechanical properties of these mixtures were studied by measuring the compressive and tensile strengths of a first series of samples developed in the laboratory. On the other hand, the thermal properties were also carried out. Prior to the analysis of the effect of the addition on the thermomechanical characteristics of the compressed earth blocks, physicochemical mineralogical characterizations of the base materials were proposed.
