Abstract

Abstract The paper is primarily focused on the description of transport of harmful species in concrete such as chlorides on one side and transport of corrosion inhibitors and nanoparticles used to diminish corrosion of steel reinforcement or seal the microstructure of concrete on the other side. The studied processes are helpful in reverting the chloride induced corrosion of the reinforcement in reinforced concrete structures. The transport mechanisms are summarized with the emphasis on their mathematical description and numerical solution. The paper shows modeling results of the processes including a comparison with experimental data on several typical examples. The efficiency of the methods is shown supported by experimental and numerical results. A good correlation of the models with experiments is achieved.

钢筋混凝土结构中氯化物腐蚀的缓解及其建模
摘要本文主要描述了混凝土中有害物质的传输,如一侧的氯化物,以及另一侧用于减少钢筋腐蚀或密封混凝土微观结构的缓蚀剂和纳米颗粒的传输。所研究的过程有助于恢复钢筋混凝土结构中钢筋的氯离子腐蚀。综述了传输机制,重点介绍了传输机制的数学描述和数值求解。本文展示了该过程的建模结果,包括与几个典型实例的实验数据的比较。实验和数值结果证明了该方法的有效性。模型与实验的相关性很好。
