【 摘 要 】

The necessity of specification of the operational humidity and its distribution in enclosing structures is justified. It is revealed that the existing experimental methods for estimating the moisture state of structures can lead to errors and require scientific development. An experimental method for determining the pattern of moistening of enclosing structures by the color indicator method is proposed. The results of experimental research and numerical calculations of the hygrothermal state of the wall fragment tested in the laboratory climate chamber are presented. It was found that the distribution of moisture can be uneven in a homogeneous structure and can be related to the surface texture of materials.
