Abstract

This study examines how remoulding affects clay’s undrained shear strength, a crucial factor affecting the stability of earthen structures. Shear strength can be considerably decreased by remoulding, which modifies the water distribution and soil structure, particularly in fine-grained soils like clays. Unconsolidated Undrained (UU) triaxial tests were used to assess changes in strength behaviour in organic clay samples that had been undisturbed and remoulded. The findings showed a similar trend in strength for remoulded sample to that with undisturbed samples, with the degree of varying depending on the initial water content and degree of soil structure disruption. In particular, for projects involving excavation, re-compaction, or ground improvement, the study underscores the significance of considering remoulded strength values in geotechnical design and the sensitivity of clay to structural changes.
