摘要
混凝土抗冻融性是衡量其在冻融循环作用下耐久性的重要指标。本文详细介绍RILEM推荐的混凝土抗冻融性测试方法-CIF法的原理、仪器设备、测试过程及结果评定,并与我国现行标准《普通混凝土长期性能及耐久性试验方法》GBJ82-1985中规定的冻融循环测试方法进行比较,以期我国有关标准制定或修订时有所参考。
Freeze-thaw cycle resistance is one of the main factors affecting the durability of concrete in cold areas. The mechanisms, equipments, test procedures and result evaluations of CIF method, which was recently recommended by RILEM, were summarized in detail, The Freeze-thaw cycle test method involved in Chinese Standard, GBJ82-1985 Test Methods of Long Term Properties and Durability of Normal Concrete, was compared with CIF Method. It is expected that, from the point of application view, this paper can be referred when the relative standards and specifications are formulated or modified.
