摘要
研究通过系统的实验分析探讨混凝土中氯离子含量对其耐久性的影响。采用电位滴定法和离子色谱法测定不同配比混凝土试件中的氯离子含量,并进行抗压强度、抗渗性、抗冻性等耐久性指标测试。结果表明,氯离子含量与混凝土耐久性呈现显著负相关。基于实验数据,建立氯离子含量与耐久性指标的定量关系模型,为混凝土结构耐久性设计和评估提供理论依据。
The effect of chloride ion content in concrete on its durability was studied through systematic experimental analysis.The chloride ion content in concrete specimens with different proportions was determined by potentiometric titration and ion chromatography,and the durability indexes such as compressive strength,impermeability and frost resistance were tested.The results show that chloride content is negatively correlated with concrete durability.Based on the experimental data,a quantitative relationship model between chloride ion content and durability index is established,which provides a theoretical basis for durability design and evaluation of concrete structures.
