Geopolymer has been developed due to its high strength, excellent durability and other series of advantages. The strength and the durability of geopolymer are correlated to the geopolymerization process inearly age.The process of the early geopolymerization and its characterization methods were summarized. The existing methods like calorimetry and dynamic rheometry as well as the advanced methods such as electron paramagnetic resonance and small angle X-ray scattering were introduced for their applicationin monitoring the early geopolymerization process. In addition, the perspective and the potential application of the proton nuclear magnetic resonance, computer simulation and other novel methods for the characterization of geopolymer were also given. This review could promote the corresponding studies on the early geopolymerization process of geopolymer and its application in practical engineering.
