标准摘要
[中文适用范围]： 该程序是一种使用加速碳化试验来评估混凝土抗碳化性的方法。 经过一段时间的预处理后，在受控暴露条件下进行测试，使用增加水平的二氧化碳，样品的垂直侧暴露于其中。 试验结果并不是为了设定性能要求，而是为了比较相同强度等级、相同环境条件下使用的不同混凝土的抗碳化性能。 [外文原描述]： This procedure specified in ISO 1920-12:2015 is a method for evaluating the carbonation resistance of concrete using an accelerated carbonation test. After a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide to which, the vertical sides of the specimen are exposed. The test results are not designated to set performance requirements but to compare the carbonation resistance of different concretes of the same strength class, which are used in the same environmental conditions.
