Abstract: The boom of building industrialization requires the strength formation of concrete as soon as possible. Compared with steam curing or autoclaved maintenance, nucleating agent in cement-based materials can not only effectively promote the hydration and hardening process, but also help to modify the interface structure and improve the durability. Therefore, nucleating agent is widely used in practical engineering and has attracted great attention. This review offered a retrospection of research efforts on the nucleation mechanism of different nucleating agents, namely inorganic salt nucleating agents, organic matter nucleating agents, nanomaterial nucleating agents and compoundnucleating reagents. The thermodynamics and kinetics characteristics of nucleation behavior were analyzed in detail. Then the influences of temperature, dosage and particle size on the nucleation were discussed. Subsequently, the effect of nucleation on the properties of cement-based materials were summarized. Finally, the challenges of nucleating agent development and the possible direction of further research were proposed. The purpose of this study is to provide reference for the efficient utilization and in-depth study of nucleating agents.

Key words: cement-based material, nucleating agent, mechanism, thermodynamics, kinetics, nucleation rate
