Abstract: This article presents the results of an experiment carried out in laboratory which aims at finding an experimental method to determine the mechanic behavior of compressed earth blocks through a very simple compressive test. As a matter of fact, the evaluation of the deformation of blocks under a progressively increasing load, by the means of a load cell and the Linear Variable Displacement Transducer (LVDT) put together on a manually operated press, has indeed enabled us to realize a strain-stress curve. Here, the analysis of this curve shows that the mechanic behavior of the earth blocks in compression is pseudo-elastic and ends off by a macro-brittle rupture because the stress is homogeneously distributed all over the surface of blocks. Therefore, we can use this device to draw up the behavior’s law of compressed earth blocks.
