Summary

The variability of soil mechanics parameters with inorganic salts (Na-, K-, Mg- and Ca-chloride) in different concentration were examined for three almost monomineralic clays (bentonite, illite, kaolin) and on clays with different mineralogical compositions (London Clay, Quick Clay).

The mineralogical-chemical tests consisted of the determination of the clay mineralogical composition, of the content of calcium carbonate and organic matter, of particular anions and cations, of the cation exchange capacity, and of the specific surface area. The soil mechanics behaviour was characterized by the study of the grain density, grain size distribution, ATTERBERG consistency limits, plasticity index, water absorption coefficient (ENSLIN test), stiffness and swelling modulus (oedometer test) and shear strength (direct shear test).

Résumé

La variabilité des paramètres de mécanique des sols causée par des sels inorganiques (chlorures de Na, K, Mg et Ca) en concentrations différentes a été examinée sur trois argiles quasi-monominérales (bentonite, illite, kaolin) et sur des argiles de compositions minéralogiques différentes (London Clay, Quick Clay).

La recherche portait sur la détermination de la composition minéralogique des argiles, les teneurs en carbonate de calcium et en matières organiques, les anions et cations particuliers, la capacité des cations échangeables et la surface spécifique. Les propriétés mécaniques des sols ont été caractérisées par l’étude de la densité des grains, la courbe granulométrique, les limites de consistence d’ATTERBERG, l’indice de plasticité, le coefficient d’absorption d’eau, le module de rigidité et le gonflement (essai oedométrique), la résistance au cisaillement (essai de cisaillement direct).
