Abstract: 
Into porous material of concrete structures can penetrate moisture in liquid or gaseous form. Humidity affects the physical properties of building material. To express the negative effects of moisture on building materials or building structures more accurately, it is needed to use the most accurate method of detecting moisture diffusion. Capillary conductivity is influenced in dependence not only at external fluids and change of heat, but also by the processes inside the porous structure. These influences should be explored in text of European standard EN ISO 15026 is informative link that presents the description of the distribution of moisture in porous material based on measurements using NMR (Nuclear Magnetic Resonance), which is essentially a curve of wetting of material in time intervals. The aim of this paper is to present information about detection of distribution of moisture in concrete by means of EMWR (electromagnetic microwave radiation) and to record moisture curve in 3D for calculation of capillary conductivity coefficient and his dependence on moisture by weight.
