Isotropic consolidation of clay can be obtained in the triaxial apparatus under equal all-round pressure.
If the present effective stress is the maximum to which the clay has ever been subjected, it is called normally consolidated clay
If the present effective stress in the past was more than present effective stress, it is called over-consolidated clay
