适用范围：This European Standard specifies an accelerated laboratory method for measuring the resistance against carbon dioxide penetration through repair products and systems, as defined in prEN 1504-3. The method is based on measurement of the depth of carbonation of the sample in a concentrated carbon dioxide atmosphere over a fixed time interval. The method is suitable for assessing the performance of repair grouts, mortars and concretes without a protective coating system applied. The method does not measure the resistance to reduction in pH-value that may occur by absorption of other acidic gases (e. g. SO2, HCl).#,,#
