摘要
为了评定制备的混凝土抗氯离子侵蚀的耐久性质量,使氯盐侵蚀下工程结构所使用的混凝土耐久性满足该结构的设计使用寿命,本文依据概率论相关知识,通过评定抽检试块的ASTMC 1202的6 h电通量是否满足电通量限值来判断配置的混凝土耐久性质量,进而提出了三种不同情况下的混凝土耐久性评定方法。通过算例分析表明,该方法可以根据电通量的限值及抽检试块的电通量实验数据来评定某批次的混凝土耐久性质量,为工程建设的使用提供依据。
This paper proposed a methodology of evaluation durability for concrete in marine environment to meet the design service life requirement of the structure.The durability of concrete is judged by the test result of 6-hour charge passed of ASTMC 1202 compared with limiting value defined in the current specification.Three evaluation methods of concrete durability under different conditions are put forward.The case study shows that the method can help evaluation of durability quality of concrete,which provides a basis for the use of Engineering construction.
