Soil cement has been the typical material for the pavement and soft ground improvement. It has not been used up to date because that quality control is not easy and durability is not long enough for practical application. Since environmental influence is important, the application of high strength soil cement pavement has been increased for pedestrian roads of the garden, golf courses and sidewalks recently. In this study, the reference table was suggested for mixing design with appling statistical experimental technique to reference table. The reference table showed the relationship among improved strength, Soilcrete stabilizer, fine sand ratio and superplasticizer agent. The objective soil used in this study was the soft marine clay that is widely found in Korea, the compressive strength range of improved soil was between $50{\sim}150kg/cm^2$.

In this paper, the effect of ground improvement and the countermeasure for the increase of strength in soft ground (wasted fill, marine clay) was studied through utilization of Soilcrete Cement as a material of ground improvement. Soil samples were obtained from $\bigcirc$$\bigcirc$$\bigcirc$ sanitary landfill to assess the applicability of the clay liner using Soilcrete Cement. Several laboratory tests were performed with the samples and skin corrosion tests of steel pipe covered with Soilcrete Cement were performed. As a result, Soilcrete Cement is considered to be applicable to the construction site and to be effective for the prevention of the corrosion of the steel pipe.
