Abstract: “The physical properties of clay are of extreme importance in soil engineering and are largely controlled by reactions in which clay plays a leading part. Kaolin clay has been widely used both in fundamental studies of soil behavior and in physical model tests. In this paper, compression and shear behavior of reconstituted consolidated kaolin clay specimen reinforced with sand compaction pile (SCP) is examined by using consolidated undrained triaxial tests. The aim of this study is to study the behavior of soft cohesive soil reinforced with different diameter SCPs by observing the change in pore pressure during consolidation and undrained shear strength of the composite ground with/without smear. The experimental results show that the mechanical properties of soft kaolin clay can be tremendously improved with this ground improvement technique”
