An experimental investigation of the behaviour of artificially cemented soil cured under stress.

The article presents an experimental investigation of the behaviour of artificially cemented soil cured under stress. It is indicated that the specimens cured at confining pressures of 50 kPa have larger normalised yield and state boundary surfaces. With regards to samples cured on the isotropic intrinsic compression line, a single state boundary surface is determined, independently of the shearing confining pressure. The effect of volume can be normalised when curing on the normal compression line. The extra strength imparted to the soil may attribute to the lower curing void ratio. The data indicate that the unloading events in the samples cured at higher stresses do not affect the subsequent behaviour.
