Current findings with respect to the XF2 freeze/thaw test method

Freeze/thaw resistance at moderate water saturation levels

Generally accepted, internationally recognized methods (CIF and CDF) exist for testing the freeze/thaw resistance of concrete at high water saturation rates irrespective of the simultaneous action of de-icing salts. These methods assume that concrete is sufficiently resistant to damage caused by freezing water if the degree of water saturation remains below a critical threshold even under permanent exposure to water. These tests are also suitable for demonstrating the influence of carbonation on freeze/thaw resistance. In the past, the descriptive specifications in EN 206-1 and DIN 1045-2 were...
