本技术规范描述了用水和氯化钠溶液测试混凝土的抗冻融抗性。它可以用于比较新成分或新的混凝土组合物与已知在当地环境中给出足够性能的组分或具体组成，或者根据当地经验对某些绝对数值评估测试结果。 外推测试结果以评估不同的混凝土，即新成分或新的混凝土组合物，需要专家评估。 注意在某些情况下，测试方法可能不适用于测试特殊混凝土。高强度混凝土或可渗透混凝土。在这些情况下，结果需要谨慎对待。此外，本文档中包含的测试方法可能无法标识偶尔受到限制的聚合。 通过三种测试方法获得的结果之间没有确定的相关性。所有的测试都会清楚地识别出贫穷和良好的行为，但是他们对边际行为的评估有所不同。对测试结果应用不同的验收限值可以评估不同程度的暴露严重程度。测试程序的参数更改可能有变化

This Technical Specification describes the testing of the freeze-thaw scaling resistance of concrete both with water and with sodium chloride solution. It can be used either to compare new constituents or new concrete compositions against a constituent or a concrete composition that is known to give adequate performance in the local environment or to assess the test results against some absolute numerical values based on local experiences. Extrapolation of test results to assess different concretes, i.e. new constituents or new concrete compositions, requires an expert evaluation. NOTE In some cases the test methods may not be suitable for testing special concretes e.g. high strength concrete or permeable concrete. In these cases the result needs to be treated with caution. Also, the testing methods included in this document may not identify aggregates that are subject to occasional ‘pop-outs’. There is no established correlation between the results obtained by the three test methods. All tests will clearly identify poor and good behaviour, but they differ in their assessment of marginal behaviour. The application of different acceptance limits for test results enables assessment for different degrees of exposure severity. Change of parameters of the testing procedure may have artefacts, some of which explained in Annex A.
