As a cutting-edge technology in the field of cement-based materials, early carbonation curing enables industrial carbon sequestration and functional modification, and the optimization of process parameters is the key to advancing the development of this technology. This paper reviews the mechanism of action and influencing factors of early carbonation curing (including moisture content, carbon dioxide concentration, pre-hydration degree, etc.), its effects on the mechanical properties and durability of materials, as well as the resulting changes in microstructure. Meanwhile, this review also covers content such as the hydration–carbonation coupling mechanism, mentions the relevant conditions of carbonation products and microstructure, analyzes the performance enhancement of the interfacial transition zone (ITZ), and provides relevant support for the low-carbon development of cement-based materials by combining the application practice of prefabricated components and the comparison of technical routes. Although early carbonation can significantly improve material properties and optimize microstructure, current research still has shortcomings: the exploration of mineral carbonation–hydration activity, microstructure evolution law, and product combination mechanism is relatively insufficient, and the understanding of carbonation–hydration coupling kinetics is still not in-depth enough, all of which are areas requiring further research in the future.
