Abstract

Using the theory of generalized conductivity and geometric modeling of the structure of wet capillary-porous materials, dependencies were obtained for calculating their effective thermal conductivity. Depending on the values ​​of the moisture content of the pores, the limits of application of the obtained formulas are established. On examples for clay bricks, the features of the calculation of wet capillary-porous materials are demonstrated. It has been established that the results of calculations quite accurately predict the experimental data.
