In this study, an immersion test using high concentration of magnesium chloride solution was carried out to develop an accelerated deterioration testing method. This test will help to investigate the deterioration rate and the mechanical properties of deteriorated cement stabilized soil quickly. In addition, unconfined compression tests were performed on the deteriorated stabilized soil specimens under magnesium chloride solution and normal concentration of artificial seawater to examine the difference in strength characteristics, respectively. As a result, it was confirmed that the evaluation method of the deterioration rate shown in the previous studies can be applied even when high magnesium chloride solution is used. It was shown that the promotion method using high concentration of magnesium chloride solution matches the reduction rate of unconfined compressive strength and deformation modulus within the range of 6% and 2% respectively, as compared with the case of using artificial seawater.
