Abstract Durability problems such as premature failure of concrete structures and routine maintenance have drawn great attention in recent years. Chloride ion transport is one of the important factors determining the service life prediction and durability evaluation of reinforced concrete structures. Due to the fact that cement-based composite materials are difficult to reach saturation during the actual service of structural engineering, more and more people have studied the transport properties of chloride-based materials in cement-based materials in unsaturated state in recent years.
In the past few decades, there have been various experimental methods for testing chloride ion transport, such as natural diffusion, electromigration, electrical resistance, and pressure infiltration. Although the natural diffusion method is in line with the actual situation, the operation is cumbersome and it is very time consuming to achieve steady state diffusion. In order to accelerate the migration of chloride ions, the researchers proposed an electric acceleration experiment and a method of adding pressure. In addition to the traditional chloride ion transfer experiments, some new experimental methods have been proposed, such as the half-cell method, to determine the chloride ion distribution according to the elemental tracer method.
In addition to experiments, models can be used to simulate the transport of chloride ions in unsaturated cement-based composites. According to the model, Fick's law, which considers the diffusion of chloride ions, and diffusion-convection models considering diffusion and convection coupling are considered. In addition, considering the influencing factors such as humidity, dry-wet alternation and water molecule transport, the researchers established a chloride ion transport model from different angles.
In this paper, the transport properties of chloride ions in unsaturated cement-based composites are reviewed, including: chloride ion transport experiments, chloride ion unsaturated transport models, and chloride ion transport factors. Finally, the existing research is summarized: the transmission performance of unsaturated cement-based composites depends largely on the moisture content of the material; below the critical saturation, the chloride ions cannot be transported due to the absence of moisture-connected pores; the admixture concrete has a smaller chloride ion diffusion coefficient than OPC concrete; the diffusion-convection model is more suitable for unsaturated cement-based materials. Looking to the future, simple and accurate experimental methods are needed to consider the impact of various factors on chloride ion transport.
