溶液成分对混凝土中氯离子扩散系数影响的研究综述

摘要

The influencing mechanism of the solution composition on the chloride diffusivity coefficient in concrete was summarized based on the diffusion mechanism of the chloride in electrolyte solution and the properties of concrete. Some test methods applicable to study the influence of the solution composition on the chloride diffusivity coefficient in concrete were introduced. The worldwide achievements of the researches on influence of solution composition on chloride diffusivity coefficient in concrete were reviewed. The disadvantages of the existing test methods were put forward. On such a basis, some key problems were proposed.%从氯离子在电解质中的扩散机理出发,结合混凝土性质,概述溶液成分对混凝土中氯离子扩散系数的影响机理.介绍适用于研究溶液成分影响的氯离子扩散系数的试验方法.总结国内外关于溶液成分对混凝土中氯离子扩散系数影响的研究成果,指出现今一些试验研究中的不足,并在此基础上提出有待深入研究的问题.
