Abstract: The efficient and rational use of pozzolan materials is an important way to achieve environmentally friendly and high performance concrete, while the scientific and accurate evaluation of activity degree is one of the keys to improve its comprehensive application effect. Through the study and analysis of domestic and international literature, the main activity evaluation methods of pozzolan materials, such as chemical test method, physical test method, microstructure analysis method and kinetic model method were outlined. The theoretical basis and applicable characteristics of various evaluation methods were discussed and analyzed. Finally, the shortcomings of the current evaluation were discussed, aiming to provide a reference for the efficient utilization and in-depth research of pozzolan materials.

Key words: pozzolan, activity evaluation, chemical test method, physical test method, microstructural analysis method, kinetic model method
