ABSTRACT
Ground Improvement using Deep Cement Mixing (DCM) is commonly used to enhance properties of in-situ soft clays. Properties of DCM are often highly variable in intensity and in spatial distribution, posing significant challenges in the analysis and design of geosystems when these man-made admixtures are used. This paper presents spatial variability results obtained from laboratory tests carried out from samples acquired from in situ DCM. A project in Singapore where over 700.000 m3 of DCM was installed is first introduced following by the results of the horizontal and vertical scale of fluctuation. Finally, some recommendations are drafted based on the results of the DCM`s scale of fluctuation presented in this paper for a more comprehensive and sustainable design.
