Stress-Deformation Behavior Under Anisotropic Drained Triaxial Consolidation of Cement-Treated Soft Bangkok Clay Academic Article uri icon


  • In this study the compression behavior of high water content cement-treated soft Bangkok clay is further investigated by conducting a constant stress ratio (CSR) test at various stress ratios (η). The test utilized cement-treated clay specimens with cement contents (Aw) of 10% and 15%, each of which was in combination with 100% and 130% total clay water contents. The test results confirmed that the ratio of after-curing void ratio to cement content (eot/Aw) can effectively characterize the compression behavior of cement-treated clay. The specimens with higher values of eot/Aw yielded higher volumetric and shear strains at the same stress ratio. While those with lower values of eot/Aw resulted in lower shear strains, with consequent higher values of strain increment ratios (dεv/dεs) both before and after transitional yield points. Significantly, the eot/Aw ratio has described the relationship of the compression yield loci of cement-treated clay at various stress ratios and mixing conditions.
