英文摘要	The influence of hydroxyl aluminium on the mechanical and physical characteristics of montmorillonite clay was examined in this study. Hydroxyl aluminium-modified and unmodified montmorillonite samples were examined using X-ray diffraction(XRD), scanning electron microscopy (SEM), hydrometer analysis, unconsolidated undrained (UU) triaxial strength tests, unconfined compressive strength tests, Atterberg limit tests, swelling potential tests and other evaluation techniques. The results indicated that the hydrophilic nature and the swelling and shrinkage properties of the montmorillonite clay changed drastically as a result of modification with hydroxyl aluminium. The free swelling ratio of the clay was reduced sharply, and its particle size gradation and strength characteristics were greatly improved by modification with hydroxyl aluminium. The proportion of clay-sized particles decreased dramatically, and the proportion of silt-sized particles increased. The results of this study suggest that hydroxyl aluminium influences the mechanical and physical properties of montmorillonite clay by physicochemical interactions.
