• This paper describes a plasticity based constitutive model for the description of cement treated clay. The model uses a bonding stress ratio m and λ'(p', e) for the simulation of cement treated clay. These parameters are used to simulate the increase in the initial stiffness and shear strength of the material and subsequent progressive reduction in stiffness and strength due to breaking of the bonding as a result of shear straining. The bonding stress ratio m takes into account the bonding effect among soil particles and the degradation of bonding with confining pressure and shear strain. The model assumed that the strength and volume change of the cement treated clay are related to the critical state parameter λ'(p', e). It is demonstrated that the model can predict stress and volume change of cement-treated soils over a wide range of confining pressures. The model shows reasonably good match with the observed response and the model parameters can easily be obtained from traditional laboratory tests.
