Abstract (EN): This paper highlights the importance of the porosity/cement index on the evaluation of the geomechanical properties of soil-cement mixtures as a contribution to analyse these materials. This index is defined as the ratio between porosity and volumetric cement content combining the degree of compaction with the cement content. The relevance of these two parameters is defined by an exponent to the volumetric cement content which changes with the type of soil. This paper results from a broad experimental program with unconfined compression tests, indirect tensile tests, triaxial tests and oedometer tests, which were all analysed by this index adjusted by a specific exponent value. The (tensile and compression) strength, the (elastic and initial tangent) stiffness, as well as the compressional behaviour are conveniently represented by this index and a different behaviour is observed when this index is changed.
