Laboratory Investigation of the Effect of Deep Soil Mixing Method on Engineering Properties of Soft Clay Stabilized by Slag and Lime
Soft clayey soil generally has high compressibility and low strength. Presence of this soil type in the site of civil projects can always be a challenge for construction issues. Soil stabilization is one of the useful ways to improve problematic soils. Cutter Soil Mixing (CSM) is almost a new method for deep stabilization. This experimental study, investigate the effect of different depths on soft clay properties which stabilized by CSM method. To simulate various depths and related surcharge pressures, new devices were designed, modified and used for laboratory tests. Moreover, mixture of blast furnace slag and hydrated lime slurry was used in this method for the first time. The samples were cured for 28 and 56 days under various surcharge pressures, which actually represent different depths. The results revealed that by increasing the depth, mositure content and saturated/dry densities of the samples were decreased and increased respectively. In addition, by passing the critical depth, fewer changes were obsorved in the moisture contents and saturated/dry densities of the samples. Finally, the strength parameters of stabilized samples were icreased significantly.
