ABSTRACT
This study investigates the effect of curing stress on the mechanical and microstructural properties of cement-stabilized marine clays, extending beyond conventional strength metrics. Two marine clays (CL and CH) were stabilized at high water contents using two cement dosages: one in the inactive zone (minimal effect) and one in the active zone (significant effect). Samples were cured under drained conditions for 7 days at stresses of 0, 50, 100, 200, and 400 kPa. While previous studies focused on compressive and shear strength, the present study also explores tensile strength, which is less documented. The research examines two stabilization mechanisms—consolidation mode and self-stress mode—assessing their relevance to the clay type and cement dosage. Findings aim to improve the understanding of the mechanical behavior of stabilized marine clays for efficient stabilization without excessive cement use, promoting sustainability by avoiding overdesign driven by conservative strength underestimations.
