摘　　要：阻锈剂技术是抑制混凝土中钢筋锈蚀的重要途径,但传统阻锈剂的应用仍然面临功能单一、与混凝土的兼容性不佳、环保性和有效性难以兼顾等问题。将阻锈剂装载入载体中,以载体负载阻锈剂(Carrier-loaded corrosion inhibitor,CLCI)的形式将阻锈剂“间接”掺入混凝土,能够在避免阻锈剂原有缺陷的基础上,发挥载体的特有功能。本文围绕CLCI的离子固化、缓释效应、智能响应、pH自免疫系统、载体吸附效应等功能机制,结合CLCI对水泥基材料性能的影响,系统综述了CLCI的研究进展。最后,对其在混凝土中的研究和应用进行了展望,并提出了需要解决的问题,以期为CLCI在混凝土工程中的应用提供更多可能性。Corrosion inhibitors provide an important way of protecting concrete steel bars from corrosion,and they have always been a research hotspot in the field of corrosion inhibition.However,the application of corrosion inhibitors still faces several problems,e.g.,single performance,poor compatibility with cement-based materials,and difficulty in balancing environmental protection and effectiveness.A corrosion inhibitor is‘indirectly’mixed into concrete in the form of a carrier-loaded corrosion inhibitor(CLCI),which not only avoids the original defects of corrosion inhibitors,but it also plays the unique function of the carrier.In this paper,we systematically summarize the research progress of CLCIs in reinforced-concrete environments from the perspectives of the action mechanism of ion curing,slow-release,intelligent response,the pH autoimmune system,and the carrier adsorption effect and its influence on the properties of cement-based materials.Finally,research and application prospects of CLCI in concrete are detailed,and the problems to be solved are put forward to illuminate more possibilities for the application of CLCI in concrete engineering.
