混凝土抗快速冻融循环的能力是混凝土耐久性的一项重要指标,它与混凝土构筑物(如大坝、桥墩等)的安全性和经济性密切相关。因此,无论是混凝材料研究部门,还是构筑物的设计及施工部门,对此项指标均很重视,都希望通过试验得出该指标的准确结果,以指导工作。所以快速冻融试验机就成了上述部门不可缺少的设备。但由于我国机械工业的门类不全,许多试验设备没有产品供应,使用者不得不自己制造,冻融机的情况就是这样。我国的快速冻融设备只有为数不多的大研究 The ability of concrete to withstand rapid freeze-thaw cycles is an important indicator of concrete durability. It is closely related to the safety and economy of concrete structures (such as dams, piers, etc.). Therefore, whether it is the research department of concrete materials or the design and construction department of a structure, this indicator has attached great importance. It is hoped that the accurate results of this indicator will be obtained through experiments to guide the work. Therefore, the rapid freeze-thaw tester became an indispensable device for the above-mentioned departments. However, due to incomplete categories of machinery industry in China, many test equipments do not have product supply, and users have to manufacture them themselves. This is the case with freeze-thaw machines. China’s rapid freezing and thawing equipment has only a few large studies
