摘   要：传统负载型阻锈剂在混凝土中存在迁移能力弱、靶向性差、利用率低的问题。为解决上述技术难题，国内外学者借鉴医学领域磁靶向药物中的磁迁移技术，将其引入混凝土腐蚀防护领域，通过磁迁移技术赋予负载型阻锈剂靶向迁移与可控释放功能。基于此，本文结合磁靶向药物的研究现状，系统综述了磁迁移靶向防腐材料应用于钢筋混凝土腐蚀防护领域的可行性，梳理总结了该类材料的分类、合成、微观形貌及适用工况。依据功能载体类型，可将磁迁移阻锈剂体系划分为微胶囊型、层状双氢氧化物（Layered double hydroxides，LDH）型与MXene型三类。同时，本文深入剖析了磁迁移技术在钢筋混凝土实际工程应用中面临的关键问题，并针对性地提出了后续研究的重点方向。综述成果可为磁迁移靶向防腐材料在钢筋混凝土防腐领域的深化研究与工程应用提供参考。Abstract: Conventional carrier-based corrosion inhibitors suffer from weak migration capacity, poor targeting performance and low utilization efficiency in concrete. To address these technical challenges, scholars worldwide have introduced the magnetic migration technology adopted in magnetically targeted drugs in the medical field into the field of concrete corrosion protection, endowing carrier-based corrosion inhibitors with targeted migration and controlled release functions. On this basis, combined with the research progress of magnetically targeted drugs, this paper systematically reviews the feasibility of applying magnetic migration targeted anticorrosive materials to the corrosion protection of reinforced concrete, and summarizes the classification, synthesis methods, microscopic morphology and service conditions of such materials. According to the types of functional carriers, magnetic migration corrosion inhibitor systems can be classified into three categories: microcapsule type, layered double hydroxides (LDH) type and MXene type. Meanwhile, this paper deeply analyzes the key problems restricting the practical engineering application of magnetic migration technology in reinforced concrete, and puts forward targeted suggestions on future research priorities. The findings of this review can provide a reference for the in-depth research and engineering application of magnetic migration targeted anticorrosive materials in reinforced concrete.

There is an urgent need to revise the standard to promote the high-quality development of the power industry. The edition of GB/T 4623—2025 Circular concrete pole is based on the actual production and usage status of circular concrete poles in China, with reference to advanced production technologies from related foreign industries, and taking into account the industry’s needs for green and low-carbon solutions, high performance, automation, and internationalization. To facilitate accurate understanding of the specific meanings of the standard’s provisions by its users and to ensure proper implementation of its requirements and regulations, the background and significance of the revision were introduced, and an interpretation of key provisions of the standard was provided. The new edition was issued on October 31, 2025, and will be implemented on May 1, 2026. Following the issuance and implementation of the new edition, it will effectively enhance the product quality and service performance of concrete poles, broaden their application fields and market space, support the green and sustainable development of enterprises, and promote the internationalization of industry products and foreign cooperation.
