ISO 1920-12:2015 PDF Download

The ISO 1920-12:2015 standard outlines a testing method for determining the carbonation resistance of concrete through an accelerated carbonation test. This test involves subjecting concrete specimens to controlled exposure conditions with an increased level of carbon dioxide on the vertical sides of the specimen. The specimens undergo a preconditioning period before the test is carried out.

It is important to note that the results obtained from this test are not used to establish performance requirements. Instead, the purpose is to compare the carbonation resistance of different concretes that have the same strength class and are utilized in similar environmental conditions. This standard provides a standardized procedure to assess the carbonation resistance of concrete, allowing for comparisons and evaluations to be made between different concrete compositions.
