Determination of Concrete Resistance to Corrosive Effects of Water with Aggressive CO2 Using Model Mortars

The paper deals with an experimental determination of resistance of concrete to the corrosive effects of demineralised water with aggressive carbon dioxide. Three types of concrete were used for the experiment, one designated for reference, another one contained a crystallising admixture, and the third type contained admixtures and was designed to be very resistant. The actual tests were, however, not conducted directly on these concretes but on model mortars derived from those concretes. The paper provides reasons why the tests specimens were produced from the model mortars and not from the given concretes. The conclusion of this paper presents not only the results of the described experiment but also comparisons with the results of previously conducted and published tests.
