Abstract

 In case of application of magnesium oxide (MgO) for field of soil improvement, it is experientially known that the manufacturing process of MgO has serious influence on its performance and engineering properties of improved soil. In this study, for investigating the function of MgO in soil improvement field, typical MgO samples which have two different manufacturing process were applied to three soil samples of loamy soil, decompose granite soil and alluvial soil. Consequently, From the results, it is found that the difference in chemical reaction rate due to the variation of specific surface of MgO samples remarkably effects on the improved soil strength, and carbon dioxide in the air may not affect the increasing of improved soil strength.
