The aim of the study is to assess the energy efficiency potential of the additive structure under study based on a more detailed analysis of the data obtained from the experiment in the climatic chamber and the thermal imaging performed. Previously, this sample was tested in climatic chambers. The object of the study is a modular wall panel made on a 3D printer. However, it takes much longer to reach the maximum concentration of chloride ions at the surface of steel reinforcement in concrete with a hydrophobizer, therefore, corrosion processes will begin to develop later. Corrosion of reinforcement in cement concrete without the addition of a hydrophobizer proceeds 1.3 times faster than reinforcement in hydrophobized concrete. The calculated corrosion rates of steel reinforcement in cement stone have small values, but over time aggressive particles will accumulate near the surface of the reinforcement, which will contribute to the intensive development of corrosion processes. The electrochemical behavior of steel reinforcement in conventional and hydrophobized concrete was evaluated using polarization measurements. Breaking of the passivity of reinforcement in cement stone without the addition of calcium stearate occurs after about 6 months of exposure to an aggressive environment, in hydrophobized cement stone after 9 months of liquid corrosion. Corrosion studies of steel reinforcement in cement stone were carried out under the conditions of exposure to a 2% MgCl2 solution. % was introduced into the cement paste at the preparation stage to ensure volumetric hydrophobization. To increase the durability of reinforced concrete products, calcium stearate in an amount of 0.7 wt. The study of the reasons for shortening the period of concrete protection of steel reinforcement and the development of ways to increase its duration are the basis for increasing the durability of reinforced concrete products and structures. The contributions, which were selected by means of a rigorous international peer-review process, highlight numerous exciting ideas that will spur novel research directions and foster multidisciplinary collaborations. Intended for professional builders, designers, and researchers. The book covers a wide range of topics including the theory and design of capital construction facilities, engineering, and hydraulic structures development of innovative solutions in the field of modeling and testing of reinforced concrete, metal, and wooden structures, as well as composite structures based on them investigation of complex dynamic effects on construction objects, and many others directions. This book gathers selected contributions in the field of civil and structural engineering, as presented by international researchers and engineers at the International Conference on Materials Physics, Building Structures and Technologies in Construction, Industrial and Production Engineering (MPCPE), held in Vladimir, Russia, on April 26–28, 2022.
