Abstract: Significance Ohmic heating (OH) curing is a novel method for cement-based materials that utilizes the electrical conductivity of the materials for curing. The temperature of the materials can be increased as the electric current passing through the mateial will generate ohmic heating, resulting in the rapid strength formation. Compared to other curing methods, research on OH curing is still in the early stage. To help researchers better understand the application of this method in the curing of cement-based materials, this article reviews the performance development patterns of OH cured cement-based materials. Progress OH curing is an efficient method for the fabrication of cement-based materials, which can improve the mechanical strength and hydration degree of cement-based materials in complex environments. Cement-based conductive materials exhibit higher curing efficiency under OH curing, because the use of conductive fillers can significantly enhance the electro-thermal properties for the materials. Additionally, OH cured cement-based materials still possess self-sensing characteristics after long-term curing, laying the foundation for their efficient and multifunctional use throughout the curing-service process. Conclusion and Prospects OH curing can achieve the rapid and high-quality fabrication of cement-based conductive materials in extreme environments, and is promising to address the issue of on-site fabrication for high-performance concrete. OH curing demonstrates advantages such as high efficiency, low energy consumption, and simple operation. It provides new ideas for the intelligent construction, health monitoring, and emergency repair of concrete, with broad application prospects. However, its application at the structural level is still in the initial stage, and its multifunctionality still has room for further development.
