Abstract
The paper presents first attempts to study the humidity detection and interpretation using NMR-techniques at concrete speciman loaded with humidity in the range 0 - 4.5%. Depending on the statistical model of the spin relaxation of H-protons two types of relaxation lows are found and interpreted. It is assumed that two binding states of water are separeted in the free induction decay. A one-sided NMR-pick-up technique for future experiments is presented.
