Influence of Soil–Cement Columns on Load-Deformation Behavior of Soft Clay
Being a challenge to deal with structural foundations in soft clays, several techniques were promulgated across the world. This paper presents the load–settlement behavior of soft clay provided with soil–cement columns in test tanks. This study revealed that the load-carrying capacity of clay bed with soil–cement columns increases with increasing initial clay consistency and it is increased by about 3.5 times when the consistency is increased from 0.1 to 0.5. The threshold cement content is found to be 15% for the floating soil–cement columns and a 25% replacement of cement with fly ash has shown a slight increase of about 1.15 times that of the capacity attained with cement alone. SEM and EDAX results support that there is an improvement of surrounding clay bed due to diffusion of calcium ions from the soil–cement columns.
