Use of capacitive and GPR techniques for the non-destructive evaluation of cover concrete (2008, result): “While the same frequency bands are not being utilized, it can still be noticed that the dielectric constant of concretes changes significantly and decreases from lower frequencies (in the 30–60MHz range) to higher ones (up to 1GHz), in accordance with the results from other studies [28–30].”
Non-destructive methods for measuring chloride ingress into concrete: State-of-the-art and future challenges (2014, background): “[25] humidity causes the reduction of relative permittivity and conductivity while chloride presence does not affect permittivity but increases conductivity of the material.”
Non-destructive evaluation of concrete moisture by GPR: Experimental study and direct modeling (2005, methodology): “This has been observed by some authors through concrete permittivity measurements [ 4-6 ].”
