Abstract

 Solidification of clayey soil by adding quick lime or cement materials may be inhibited due to the soil properties such as types of clay minerals, water quality of porewater. In this study, in order to investigate the mechanical property of lime and cement stabilized clay containing magnesium salts, unconfined compression test was conducted. Subsequently, accelerated deterioration test which was simulated seawater environment was performed to investigate the effect of concentration of magnesium salts on deterioration behavior of stabilized clay. As a result, it is verified that magnesium salts have functions to decrease the strength and accelerate the progression of deterioration of stabilized clay. Additionally, a new parameter that can evaluate the deterioration rate of stabilized soil containing magnesium salts regardless of stabilizer types was proposed.
