Ceramic technology is based on three requirements: maintaining the product properties on the required level, reduction of energy costs, optimization of raw materials consumption and technological parameters. It is possible to obtain a product with improved operating abilities, at the same time optimizing the energy consumption, with the use of modern methods of thermal treatment, which include a combination of burning mechanisms in one technological conversion.The service durability of products is determined by the simultaneous influence of the factors, which are characterized by the properties of raw materials, the conditions of molding powder preparation, molding and thermal treatment. The usage of innovational technological methods allow to reduce the duration of the main energy consuming operations — the process of powder preparation can be reduced from 8—12 hours (traditional technology) up to 2—3 minutes, and the process of drying and burning from 2—3 days to 1—1.5 hours. The quality of ready products remains high.Ceramic tiles are primarily used as finishing material in the construction of residential, public and industrial buildings. Modern technologies of ceramic tiles provide not only crock glazing, but also applying other materials on it. This can extend the range of ceramic tiles application.

Many problems of identification of the stress-strain state against the background of the heat and mass transfer are solved through the application of constant (averaged) values of mechanical properties (elastic modulus, Poisson's ratio) and derivation of differential equations with constant coefficients. Due to irregular distribution of temperature and other factors of impact, including the moisture content, mechanical properties of many materials change significantly; therefore, the problems in question are solved within the framework of mechanics of heterogeneous bodies.
In this paper, the authors solve the classical problem of the steady-state moisture-induced elasticity of a thick-walled cylinder by taking account of the changes in the value of the elastic modulus caused by the influence of moisture. In this case, the problem is reduced to a differential equation with variable coefficients, which makes the solution more complicated though more accurate. It is proven that due regard for the heterogeneity leads to a significant increase in stresses, if compared to the solution based on the mean values of the modulus of elasticity.
