Deformation Behaviour of Cement-flyash Stabilised Silt

The deformation behaviour of a cement flyash stabilised silt was studied experimentally with a wide range of stress paths. The failure surface of the cement flyash stabilised soil was significantly more curved than the parent soil. This can be explained by the deformation behaviour. Bond breakage commenced at very low strain level, and was essentially completed at about 1% axial strain. One-way cyclic loading did not appear to induce any degradation of a sample. However, considerable degradation occurred when a sample was subject to two-way cyclic loading.
