Non destructive measurement data fusion for a better assessment of concrete
Résumé
Non destructive techniques provide many quantitative information about concrete condition (observables), which must be processed such as to give way to the indicators which are looked for. An experimental database is defined and fed with a series of NDT measurements obtained through various techniques. The methodology requires: the selection of best observables, the expression of relationships between indicators and observables and the combination of information provided by various sources. Data fusion, which accounts for uncertainties arising at various levels, offers a promising way.
