Testing of Cetris-Basic Wodd-Cement Chipboards by Using Impedance Spectroscopy after Nitrogenous Stress Cycle

Popis výsledku v původním jazyce

Impedance spectroscopy is a non-destructive testing method ranking in the electrical engineering measuring method group. It outputs data providing information on material electric and dielectric properties. Microscopically inhomogeneous materials are frequently used in the building industry. Unfortunately, the impedance spectroscopy results and their characterization on the basis of this method are not unambiguous. The frequency spectrum behavior of Cetris-basic specimens was studied by means of the NDTimpedance spectroscopy method for various water content values. A stress cycle with defined absolute water content values is described. Effects of potential dielectric losses and the redominance of the polarization and conductivity components in variousregions of the impedance spectrum are described for various water content values. So dry specimen pre-stress and post-stress liquid nitrogenous cycle tan delta(f) spectrum variances were observed.
