Mathematical model for isotropic compression behaviour of cemented soil cured under stress

Abstract

A mathematical model is proposed to simulate isotropic compression test results obtained for specimens of silty sand mixed with different cement contents and cured at different void ratios. The ability of the model to represent the isotropic test results of specimens with different cement contents cured at high and low void ratios under high confining stresses was successfully checked. The physical meanings of the parameters established by the model were also evaluated. Finally, the applicability of the model to other artificially cemented soils was demonstrated.
