ABSTRACT
Test methods used for compliance testing are intended to give a direct and reliable quantification of the concrete characteristics. However, the slow progress of deterioration mechanisms as for instance carbonation calls for accelerated test methods. Therefore, rapid chloride migration testing and accelerated carbonation testing have been established as standard procedures for quantification of chloride migration and carbonation properties respectively. For freeze-and freeze-thaw-exposure, CDF-and CIF-test appear to be adequate test methods. Due to the lack of deterioration models for these mechanisms, durability design with respect to freeze-and freeze-thaw-impact is still limited to ‘deemed-to-satisfy’ approaches.
