摘要
氯离子对混凝土结构的侵蚀主要以海水和海边的水蒸气为媒介进行。根据模拟海水及滨海环境下的盐雾腐蚀试验的研究成果,阐述了氯离子通过两种不同的状态在混凝土内部的扩散规律,为正确评估钢筋混凝土结构在滨海环境中的耐久性和制定相关混凝土结构的耐久性设计规程提供依据。
The concrete structures are corroded and eventually destroyed by the chloride ions mainly take sea water and steam as medium.This paper elaborates the diffusion rules of the chloride ions under different condition permeating into the concrete interior according to the research results of the corrosion test of the sea water and salt fog simulation,which will provide suggestions for evaluating the durability of the structures in coastal environment and working out related durability codes of concrete structure.
