摘要
为评价混凝土界面过渡区抗氯离子渗透能力,本文在已知骨料体积率及界面过渡区厚度的前提下,通过测定含骨料试件氯离子迁移系数和水泥净浆氯离子迁移系数,计算在稳态电迁移下界面过渡区的氯离子扩散系数。该计算结果可为评价现代混凝土界面的渗透性提供一定的理论借鉴。
In order to evaluate the chloride penetration resistance of concrete interfacial transition zone, under the premise of thickness of aggregate volume rate and interfacial transition zone, by measuring chlorine ion migration coefficient of specimens including aggregate and chloride diffusion coefficient of cement paste, the chloride ion diffusion coefficient of interfacial transition zone is calculated under steady state electric migration.The results can provides certain theoretical references for evaluation of the permeability of modern concrete interface.
