摘要： The present invention relates to a method of non-destructive measurement of a degree of humidity of a material (B), such as for example a mortar or a concrete in the course of drying, the method comprising: a step of emitting (S1) a radiofrequency signal (S_RF) in the material (B) through an antenna (10a, 10a') embedded in the material, a step of receiving (S2) a reflected signal (SR) in response to the radiofrequency signal emitted (S_RF), a step (S3) of frequency analysis of the reflected signal so as to determine resonant frequencies of the antenna (10a, 10a') in the material (B), and a step of estimating the degree of humidity of the material (B) on the basis of the resonant frequencies determined.
