Effect of Pore Fluid pH on the Dynamic Shear Modulus of Clay

Source

This paper presents the laboratory test results on the dynamic shear modulus of clay mineral mixture with sand under dynamic torsion loading. Various pore fluids, as reflected by pH values ranging from 2.0 to 12.0, were introduced in the soil mixtures. Both shear modulus and maximum shear modulus were computed. Consolidation pressures varying from 34.5 to 276 kPa were used. All test results are presented in graphical and tabulated forms. Comparisons of various pH values with normal conditions are made. Finally, physico-chemical concepts are used to examine the soil-pollutants interaction.
