Abstract: For high-performance concrete a good frost resistance has been often supposed from the outset due to their extreme dense pore structure. From recent fundamental investigations on high-performance concrete it can be concluded that the behaviour under freeze-thaw exposure is totally different from that of normal strength concrete. In contrast to traditional concrete, high-performance concrete with addition of additives and admixtures show on one side a higher sensitivity to differences of material composition or quality and on the other side sudden and distinctive microcracking due to internal damage. Therefore, the frost resistance of high performance concrete cannot be assessed by the design concept alone, but should be tested in advance by means of adequate test procedures like the CIF-test method (“Capillary suction, Internal damage and Freeze-thaw test”).
The paper presents examples of the great variety within the frost resistance of high strength concrete due to variation of mix design or boundary conditions. On top of this, the relationship between frost resistance, speed of saturation and pore size distribution is discussed.

Keywords: frost resistance, high-performance concrete, durability
