摘要：

Magnesium phosphate cement (MPC), a new type of inorganic cementitious material, has tremendous advantages in the fields of rapid repairment of civil structures and solidification/stabilization of hazardous wastes due to its superior performances, such as high early strength, small dry shrinkage and good durability. However, MPC often shows low workability due to its fast setting caused by the high exothermic acid-base reaction. So the research on the retardation of MPC will be a key direction for its scale application. The addition of retarders into MPC can efficiently retard the setting, thus to improve its workability. Based on the comprehensive literatures on the retarder researches of MPC, the effects of some commonly used retarders (borax (B), boric acid (BA) and sodium tripolyphosphate (STP)) on the properties (hydration heat, compressive strengths and setting behaviors) and hydration mechanism of MPC were reviewed in this paper. Finally, the advantages and shortcomings of the current retarders in the application of MPC were discussed, and the research orientation and prospect of MPC retardation are pointed out. We believe that this review can provide a literature support for the retarding research of MPC. © 2022, Materials Review Magazine. All right reserved.
