| Outline of Final Research Achievements |
In this study, in order to contribute the development of durability estimation method for chemical stabilized soil in tidal area, effects of types and adding the amount of stabilizer, salinity concentration and temperature of tidal river water on deterioration rate of stabilized soil were investigated by laboratory tests. An empirical prediction formula of deterioration rate of cement and lime treated clay under marine environment considering above factors was proposed according to experimental results. In addition, it was verified that the alteration which is generated at boundary between seawater and the stabilized soil has a protection effect against calcium leaching and mechanical deterioration of stabilized soil due to its intricate structure.
