摘　　要：对充填外加剂的功能与特性、国内外发展趋势、市场前景与需求进行了阐述和分析。报告了充填膨胀剂、充填缓凝早强剂研究实例,并对其作用机理和使用效果进行了分析和说明。提出了充填外加剂在实际工程应用中仍需要解决的一些问题,如相容性、最佳掺量研究等。Firstly, the functions and features of filling admix- tures and their developing trends at home and abroad were described and analyzed, as well as the market outlook and demands. Then the study examples of filling expansive a- gents, and set retarded and early strength agents were repor- ted, in addition, their action mechanisms and application re- sults were analyzed and explained. Finally, some unresolved problems of filling admixtures in engineering applications were submitted, such as the compatibility, the optimum mix amount, etc.
