Results show that the service life of concrete structures is determined jointly by concrete cover, chloride diffusivity, chloride binding capacity, critical chloride concerntration, structural defects and exposure conditions.
结果表明,混凝土保护层厚度、氯离子扩散系数、氯离子结合能力、临界氯离子浓度、混凝土结构缺陷和暴露条件等决定了混凝土结构的使用 寿命。
The experimental results show that Friedel’s salt is the main chloride binding product in concrete, and the chloride binding capacity of concrete is higher for concrete submerged in NaCl solution than that of concrete in the other corrosive solutions.
结果表明:混凝土在氯盐溶液中结合氯离子的产物为Friedel’s盐,其在NaCl腐蚀溶液中的氯离子结合能力最大,复合溶液和青海盐湖卤水溶液中由于硫酸根离子的存在降低了混凝土的氯离子结合能力,且随腐蚀溶液中的硫酸盐浓度增加而降低。
The influences of mineral admixture content,exposure time and curing age on the chloride binding capacity were discussed.
结果表明;随着矿物掺合料掺量的增大,粉煤灰混凝土氯离子结合能力的变化趋势是先上升后下降,矿渣混凝土的氯离子结合能力则急剧增强;混凝土的氯离子结合能力与暴露的氯盐溶液种类有关,而与暴露时间无关,并且随着混凝土的标准养护龄期的延长而不断增强。
