摘要
应用透水法、改进快速Cl-渗透法及CH2Cl2浸泡法测定了不同强度等级、不同配合比混凝土试件的渗透性。试验结果表明,透水法未考虑实际工程中混凝土所受的约束作用,其适用性对强度等级的依赖性很强;而改进快速Cl-渗透法和CH2Cl2浸泡法避免了上述缺点,且二者得到的混凝土渗透性结果具有较好的相关性。
Water penetration test, improved rapid chloride ion penetration test and dichloromethane immersion test were used to measure the permeability of concrete specimens with different strength grades and mixing proportions. The results indicated that restrained effects on the concrete structures in field engineering were not considered in the water penetration test, whose application was strongly dependent upon the strength grade of concrete. The defects mentioned above were avoided in improved rapid chloride ion penetration test and diehloromethane immersion test. Good correlation between the results of improved rapid chloride ion penetration test and dichloromethane immersion test was presented.
