Rapport: Résultats d'essais de résistance mécanique sur échantillon de terre comprimée

Brief english summary

During the last meeting of TC EBM in Marrakech in September 1995, the Public Laboratory For Tests and Studies of Morocco was committed to carrying out compression and traction tests on cement-stabilised compressed earth bricks and cylindrical samples. Such tests were also carried out by the Geomaterial Laboratory of the ENTPE in France, which is member of TC EBM. The results of these tests are presented in this paper with the aim of validating those already obtained by the ENTPE. A suitable earth material was selected to undertake this research project. Before proceeding with the cement stabilization process, organic, sulphate and chloride contents were determined. Samples were manufactured using a hydraulic machine and a specially designed steel mould. The production parameters of the cylindrical samples were the optimum water content and the static compact dry density. Other samples were obtained by assembling two halves of sawed compressed-earth bricks using the same production parameters. Curing conditions were the same for all samples before undertaking the tests. The strengths obtained were compared to those specified by the document “Proposal of standards for testing compressed earth”, which was given to the TC EBM Secretary during the September 1995 meeting in Marrakech.
