Performance Based Durability Specifications
This paper describes how worldwide efforts are being made to develop durability design approaches in order to ensure a longer life for reinforced concrete (RC) structures at the lowest cost. With the increasing use of complex concrete mixtures incorporating hydraulic and pozzolanic materials, a performance based approach seems particularly relevant for durability issues. Such an approach has been developed in France within the framework of an AFGC Working Group. It is based on key material properties called durability indicators (DI), on the specification of appropriate performance based criteria, and on the use of predictive models. The purpose of this approach is to design concrete mixtures capable of protecting RC structures against a given degradation, such as reinforcement corrosion or alkali-silica reactivity (ASR), for a target lifetime in given environmental conditions.
