剪应力作用下混凝土结构氯离子传输试验研究
Experimental Study on Chloride Ion Transport in Concrete Structure under Shear Stress
摘要
Abstract
In actual engineering, the concrete structure is subjected to normal stress and shear stress, which accelerates the deterioration of durability.However, the law of chloride ion transport under shear stress in concrete structures is rarely reported.The concrete beams were subjected to long period shear loading by innovative loading method.The law of chloride ion transport under shear stress in concrete structures was studied.The results show that shear would increase the permeability of the concrete structure, with the increasing of load level, chloride ion diffusion coefficient increased.Finally, based on the experimental datum, the mathematical model of chloride diffusion coefficient of concrete specimens under shear stress state is established, and the effect of shear stress on the diffusion coefficient of chloride ion in concrete is analyzed.关键词
