This paper summarized the research achievements and engineering experience for the quick damming technology of the MgO concrete. The characteristics of quick damming technique of the MgO concrete and its difference from traditional cylindrical pouring methods were systematically reviewed based on the fundamental theories, compensation principles, realization measures, and construction technologies. Characteristics and expansion mechanism of the MgO-type expansive agent were illustrated. The basic physical and mechanical deformation properties, characteristics and patterns of autogenous volume deformation, and its influence on numerical simulations, engineering applications, and economic benefits as well as its application conditions were introduced respectively. Finally, the paper presents the problems concerning with the designs, constructions, experiments, and rapid detection of uniformity.
