摘要：

A mathematical model for the calculation of the amount of frozen water in the porous building materials is presented in this paper. The model is based on the analysis of temperature and moisture content fields in the investigated material together with its pore size distribution function and is primarily designed for the relative assessment of building constructions. The newly formulated model is applied on several wall assemblies made of traditional structural materials and their hygrothermal performance is analyzed in terms of possible frost induced damage. Based on the model outputs some future objectives are drawn.
