Résumé :	The construction sector is the largest industrial consumer of raw materials. Like all materials, concrete has an important role to play in sustainable development through its contribution to energy saving and durability of constructions. In this context, the performance-based approach to concrete durability appears to be one of the essential tools. It enables the use of new constituents and innovative concrete mixes, while improving the level of safety for the end user. The difficulty of the performance-related design method lies in choosing the threshold value. In the equivalent durability concept the main difficulty is to define the reference concrete. In this article we propose a methodology which can be used to take into account the variability of the concrete properties when a performance-based approach is applied. The proposed methodology allows the interest of using some statistical aspects to be discussed.
