STUDY OF MOISTURE DIFFUSION IN CELLULAR CONSTRUCTIONAL MATERIALS
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
The article presents the results of studies of the kinetics of changes in the diffusion coefficients of moisture in wet cellular materials of enclosing structures of buildings, in relation to the moisture content. The presented method makes it possible to obtain the diffusion coefficients of moisture in the cellular materials in the entire range of moisture from a single experiment, which naturally lasts about 2-3 days. This makes it possible to solve the tasks of the heat and humidity regime of homogeneous enclosing structures of buildings according to equation (2), similar to the Fourier equation based on the moisture content gradient. It is necessary for multilayer structures to have boundary conditions of type IV, i.e., respectively, equilibrium moisture content at the joints of materials.
