Abstract
When chemical stabilized soil is exposed to seawater, white color sediments may be observed at boundary between seawater and the soil. In this study, in order to investigate difference of calcium leaching behavior and mechanical deterioration degree of stabilized soil due to presence of the sediments on the surface of lime stabilized clay, an immersion test which was simulated marine environment was conducted. As a result, white color sediments were generated on the surface of the lime stabilized clay specimen with relatively high stabilizer content. The sediments were estimated spherical magnesium hydroxide by scanning electron microscopy observation and elemental analysis, and it is verified that calcium leaching and mechanical deterioration of stabilized clay were suppressed due to fine structure of the sediments.
