Abstract:  Due to scarcity of land for rising population in a country like bangladesh, it is necessary to improve the soft soil to face the challenges of this problem. Soft soils are generally labeled as ‘problematic’ because of poor resistance to deformation and very low bearing capacity. Thus, improvement of the weak properties of soft soil is required, which can be achieved by adopting cement column as one of the soil improvement techniques. This paper aims to define the effect of cement column in improving soft soil and their installation technique by laboratory investigation through small scale test. To check the degree of improvement of soft ground due to the installation of cement column is the main objective of the study. A mixing machine, fabricated locally as a part of this study, is used here to provide cement column in the soft soil. Astm d2166 is used to determine the unconfined compressive strength of the reconstituted soil, which is used further to determine the bearing capacity of the soil media. The “universal testing machine” is used for determination of load-settlement behavior of the cement column improved ground. Finally, from the experimental investigation it was observed that the bearing capacity of soft ground can be increased significantly through the installation of cement column.
