triaxial compression test cement stabilization consolidation curing undrained shear strength
Undrained shear strength of cement-stabilized soil can be changed by consolidation due to overburden pressure. Effect of isotropic consolidation stress during curing on undrained shear characteristic of cement-stabilized soil was examined using triaxial compression test apparatus. A stabilized soil used in a series of tests was a mixture of sandy soil and ordinary portland cement. Triaxial compression tests (CU) were performed on the soil under conditions of different magnitudes and times of applying confining stress. The test results are compared with those of unconfined compression tests on the same soil obtained by another one-dimensionally consolidation device. Excess pore water pressure dissipates and volumetric strain becomes a constant value, as the consolidation time proceeds. Undrained shear strength of cement-stabilized soil increases with an increase in initial effective confining pressure and curing time, whereas it decreases with an increase in delayed loading time. Behavior of excess pore water pressure shows a similar tendency with that of overconsolidated clay. These exists a good correlation between triaxial compression and unconfined compression tests in terms of undrained shear strength and volumetric strain.
