Abstract:
Concerning the durability of concrete, Annex F of European Standard EN 206-1 gives recommendations for limiting values of concrete composition. These values are based on the assumption of an intended working life of the structure of 50 years. The in-situ and laboratory performance of eight concrete mixtures have been measured. The composition of these mixtures fulfills the limiting values of differenct carbonation-induced corrosion and chloride-induced corrosion exposure classes, as defined in EN 206-1. Two cements were tested a portland cement and a pozzolanic cement. The results present a set of laboratory and in-situ values that can he used as a basis for defining the performance-related design methods with respect to durability.
