Zerstörungsfreie Bestimmung von Tiefenprofilen in Baustoffen mit Hilfe von Kernspinresonanz in Aufsatztechnik
Abstract
With the aid of the one-sided access H-NMR System moisture profiles in different types of building stones could be recorded with a minimum resolvable increment in depth diredtion of 1 mm and a maximum measuring depth of 26 mm. In comparison to gravimetrical measurements it was schown, that moisture contents down to 3 vol.-% could be determined with an accuracy R-square=0,97. Building materials on wood basis -because of their high content on protons- are especially suitable for the investigation with H-NMR.
