摘要：

Moisture in building structures influences physical properties of materials and can cause their degradation. Apart from several exceptions, building materials are hardly ever dry. They always contain some moisture occurring in the solid, liquid or gaseous state. Moisture is a very variable quality with different effects on thermal and technical properties [4]. To express an anticipated negative effect of moisture on building materials related to building structures it is necessary to achieve as accurate way of determining their moisture characteristics as possible. Informative mention in conclusion of the European Standard EN ISO 15026 presents the moisture distribution and functional relation between D-w and w(s) on the basis of measurement by NMR method (nuclear magnetic resonance).
