Effects of curing stress on the stiffness of a cement-mixed sand

Research into naturally cemented soils (e.g. sandstones) has increased considerably, mostly be-cause of growing interest in offshore oil wells at depths that can, at times, exceed 1000 m. Performing tests directly with on-site soil samples is ideal. However, it's acquisition, transportation and preservation are in-credibly difficult. In order to perform the tests required for this study, the samples were made to simulate the bonding found in naturally cemented soils. Artificially cemented sands were cured under stresses of either 500, 2000 and 4000 kPa, or simply under atmospheric pressure. These specimens were then subjected to drained triaxial compression tests. The results have shown that the curing type has influence over the artifi-cially cemented sand's yield surface and stiffness. The stiffness was vastly superior in specimens cured under higher levels of stress
