为保障水工混凝土抗冻性检验的及时性，提高工程建设与运行安全，系统回顾了既有混凝土抗冻性检测方法，比较了慢冻法、快冻法、单面冻融法、抗盐冻剥蚀法的标准差异。分析了以快冻法为基础的抗冻性快速检测技术、以过程参数控制为依托的混凝土快速检测技术两个新趋势。提出了基于硬化混凝土结构参数、加速破坏试验、关键过程参数的混凝土抗冻性快速检测方法新设想，构建了专用曲线核心理念，阐明了新方法的具体应用流程，为水工混凝土抗冻性检验提供了新思路。
Abstract：To ensure the timeliness of frost resistance testing of hydraulic concrete and improve the safety of construction and operation of project, the methods for testing the frost resistance of concrete were systematically reviewed. The standard differences among slow freezing method, fast freezing method, single-sided freeze-thaw method and salt-resistant erosion method were compared. Two new trends were analyzed including the rapid detection technology of frost resistance based on the rapid freezing method and the rapid detection technology of concrete relying on process parameter control. The new ideas for rapid testing methods of frost resistance were proposed based on structures parameters of hardened concrete, accelerated destructive experiment, key process parameters of freezing and thawing. The concept of dedicated curves was established, and the specific procedures of the new methods was clarified. The work of all the above could provide new ideas for the frost resistance testing of hydraulic concrete.
