Résumé :	Assessing concrete condition is of major interest either for looking at weak or more damaged areas, or for reliability computations. NDT measurements provide a valuable way of offering a quick overview on the material condition. One of their main weaknesses is that their results cannot be directly linked with material properties. This paper presents how a collaborative research programme has been developed such as: (a) to select the best appropriate measurement techniques, (b) identify calibration laws enabling the quantitative material condition assessment, (c) identify possible valuable combinations of techniques. This strategy is applied to laboratory specimen data as well as to on site data. A focus is also placed on the reliability of the material condition assessment.
