Engineering properties of soil-cement obtained from the construction site of a liquid natural gas (LNG) station are reported in this paper. To increase the bearing capacity and to reduce settlements of the soft ground under pipeline and building loads, soil-cement columns were fabricated with mechanical deep-mixing method. Fourteen days after construction, 50 mm-diameter cylindrical specimens were drilled from the site and then tested in the laboratory. Based on the experimental results it is found that the recovery ratio varies from 71% to 90%. Shear modulus of the ground increased by about 40-140 times as a results of deep mixing. Uniaxial compressive strengths of the specimens obtained are quite scattered, however, the test results are greater than the design strength 2.0 MPa. Compressibility of the ground has reduced by 45% to 90%, as a result of ground modification.
