ABSTRACT
The properties of topsoil may be significantly improved to make it a suitable subgrade for paving or construction. Due to its compressibility, soft clay soil is a well-known example of a problematic soil. Deep soil mixing (DSM) is one example of practical and effective practice for soil improvement that increases the soil strength and decreases the soil compressibility. The properties of the improved soil column may, therefore, be affected by the original soil's characteristics, the mixing procedure, and the binder. In addition, in the presence of salty water, the effectiveness of these mixes, which are often utilized effectively in the soil improvement process under normal conditions, may be reduced. The literature on DSM in the presence of saline water is limited. This study assesses the use of lime or cement in DSM in the presence of salt water with a mixture of specific proportions depending on the grain size distribution and plasticity of the soft clay soil, permeability, modulus of elasticity, void ratio, and mineral and chemical compositions. The influence of water salts, such as SO42−, Cl−, and Mg2+ salts, on the undrained shear strength (Cu) of the soft-clay-lime/cement-stabilized soil was investigated in the laboratory. Test samples were made by combining clay soil with different lime/cement ratios and allowing them to solidify for 7, 28, and 56 d. Using unconfined and triaxial compression tests, the improvements in the compressive strengths of the test samples were evaluated.
