Performance of Concrete with an Intended Working Life of 50 Years

Relating to 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 structural service life of 50 years. The in-situ and lab performance of 8 concrete mixtures were measured. The composition of these mixtures fulfills the limiting values of different 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 lab and in-situ values that can be used as a basis for defining the performance-related design methods with respect to durability.
