This work focuses on the use of the activity parameter for theidentification of dominant clay minerals in soils. Published data fromfive samples of expansive soils, on which the clay minerals identificationhas been done using different techniques (X-Ray diffraction, FSRclassification, and the consolidation parameters), were used to calculatethe activity parameter. This geotechnical parameter, as well as otherplasticity parameters helped to determine and interpret the soilsproprieties and the principal clay mineral governing the mechanicalbehaviors of these soils. All in all, this study demonstrates that the useof the activity parameter associated with plasticity parameters (PL,LL,SL)is significantly sufficient to identify clay minerals for infrastructureprojects.
