In order to solve the problems of environmental pollution and energy consumption caused by traditional soil consolidation methods, and to understand how to use the reactive magnesia as hardener to stabilize soil by carbonation, the paper summarizes the principle of the reactive magnesia stabilizing soil based on carbonation, the influencing factors of the reactive magnesia stabilizing soil based on carbonation and the durability of the reactive magnesia stabilizing soil based on carbonation according to the existing research results.
