Cement-based materials (CBM) in humid environments, influenced by their inherent defects and the presence of pore solution, exhibit poor electrical insulation performance. Low electrical resistivity of cement-based materials poses a threat to the safety of resilient infrastructures, shortens the lifespan of materials, and increases the costs of maintenance and repair. In this work, we first elucidate two primary mechanisms for enhancing electrical resistivity: (1) inhibition of ion electromigration and (2) disruption of conduction paths. We then systematically summarize and discuss 16 potential methods for improving their electrical resistivity based on these mechanisms. It is indicated that among these 16 methods, early carbonation curing, the addition of high-activity mineral admixtures, and surface hydrophobic modification are particularly effective approaches. The combination of two or more methods can simultaneously exert their functions, thus maximizing the overall effectiveness. Future work is outlined with the aim of meeting the growing demand for cement-based materials with high electrical resistivity in the construction of resilient infrastructures.

通过离子传导机制测定水泥基材料的电阻率，以增强基础设施的弹性


水泥基材料 （CBM） 在潮湿环境中受其固有缺陷和孔隙溶液存在的影响，表现出较差的电绝缘性能。水泥基材料的低电阻率对弹性基础设施的安全构成威胁，缩短了材料的使用寿命，并增加了维护和维修成本。在这项工作中，我们首先阐明了提高电阻率的两种主要机制：（1） 抑制离子电迁移和 （2） 破坏传导路径。然后，我们系统地总结和讨论了基于这些机制提高其电阻率的 16 种潜在方法。结果表明，在这 16 种方法中，早期碳酸化固化、添加高活性矿物外加剂和表面疏水改性是特别有效的方法。两种或多种方法的组合可以同时发挥它们的功能，从而最大限度地提高整体效果。概述了未来的工作，旨在满足在建设弹性基础设施时对具有高电阻率的水泥基材料日益增长的需求。
