International Journal of Concrete Structures and MaterialsThe changes of the microscopic pore structure for concrete under cyclic axial compression accelerate chloride-ion penetration, reducing the durability of concrete structures. To address this, a chloride-ion migration experiment for concrete was conducted

Effectiveness of Small Amount of Surface Penetrant against Chloride Ion Penetration
Engineering Proceedings, 2023 To increase the durability of concrete structures, surface coating is widely used as a preventive maintenance strategy against de-icing salts. We investigated the effectiveness of a small amount of surface penetrant for chloride-induced corrosion on ...

Analysis Technique for Chloride Behavior Using Apparent Diffusion Coefficient of Chloride Ion from Neural Network Algorithm [PDF]
Journal of the Korea Concrete Institute, 2012 Dept. of Civil Engineering, Hannam University, Daejeon 306-791, KoreaABSTRACT Evaluation of chloride penetration is very important, because induced chloride ion causes corrosion in embeddedsteel. Diffusion coefficient obtained from rapid chloride penetration test is currently used, however this method cannot provide a cor-rect prediction of chloride ...

Determination of chloride ion diffusion coefficients for zinc dissolution in a low temperature molten salt [PDF]
Electrochimica Acta, 1990 Abstract The transport properties and stoichiometry of the zinc dissolution process in mixtures of aluminum chloride and 1-methyl-3-ethylimidazolium chloride were studied. A new mass transfer correlation for rotating cylinder electrodes was found for these high Schmidt number electrolytes.

Study on Chloride Ion Diffusion Model in Crack Zones of Saturated Concrete Structure
Zhongwai GongluIn order to accurately characterize the behavior of cracks in accelerating chloride ion transport on both sides of the concrete, the concept of effective influence distance of cracks was proposed, and the crack pores were non-uniformly distributed ...
