Abstract: Since the last 20 years we are leaving the security of the design or description concept, because new materials with little experience will be used for concretes in special appli-cations. Therefore, a performance concept is necessary for a reliable assessment of the durability, e.g. frost resistance of concrete. The reliable testing of the frost resistance of concrete was a problem in the past. In the case of testing three different parts have to be considered - the generation of damage, the measurement of damage and the valuation of the test result with practical experiences. The measurement of internal damage with non-destructive test method is meanwhile well known, e.g. resonance frequency, length changes and ultrasonic transit time. With these test method a sufficient precision can be expected. The significant parameter of the test, e.g. water uptake, temperature regime and uniaxial frost attack have to be defined as exactly as possible. On the basis of fun-damental research work the CIF test (Capillary suction, Internal damage and Freeze thaw test) [1,2,3,4] was developed for precise testing of frost resistance of concrete. In this paper the major influencing parameter to assess the frost resistance of concrete are dis¬cussed in accordance with correlation, practical experiences and acceptance criteria.
