The most effective way to reduce the structure mass, labor input and expenses for its construction is to use modern high-performance concrete of the classes С50/60… С90/105, which possess high physical and mathematic characteristics. One of the constraints for their implementation in mass construction in Ukraine is that in design standards there are no experimental data on the physical and mathematic properties of concrete of the classes more than С50/60. Also there are no exact statements on calculating reinforced concrete structures made of high-performance concretes.The authors present the results of experimental research of the scale effect and short-term and long-term heating up to +200 ° C influence on temperature and shrinkage strain, on strength and strain characteristics under compression and tensioning of high-strength modified concrete of class C70/85. The application of high performance concretes is challenging in the process of constructing buildings aimed at operating in high technological temperatures: smoke pipes, coolers, basins, nuclear power plants' protective shells, etc. Reducing cross-sections can lead to reducing temperature drops and thermal stresses in the structures.

The modern tendencies of construction industry development are connected with the use of new high-efficient materials with the application of resource- and energy-saving technologies of their generation. The use of industrial man-made products as the components improving the characteristics of construction products is now a promising field of research. The article presents the results of the use of waste pickling solutions of steel rolling factories, containing salts of iron as nanomodified additives for the products based on cement binder. The effectiveness of the influence of the considered additives on the structure and strength of fine-grained concrete is shown. If using this additive in the amount of 0.32 % from the mass of cement for 28 days of natural hardening, the fine concrete strength is growing by 1.8 times due to additional formation of hydrosilicates, densification of structure and reduction of the total porosity of the cement system by 2 times.

Urban conditions are characterized by geographical and climatic features, geotechnical and hydrogeological conditions. But the main features are architecture, urban planning and engineering infrastructure solutions. This includes roads, water mains, electrical networks, sewage, heating system. Saturation of urban areas by engineering services depends on the size of the city, its population and climatic conditions. Metropoles and cities with long heating season are of particular importance in terms of this issue.The article discusses the need for full-scale investigation of the distribution of temperature field in the soil and underlying sediments during the engineering and environmental surveys in urban environment. In order to study the transfer of heat and moisture in clay soils and to assess its influence on their physical and mechanical properties the authors propose the principles of interaction simulation of the soil and the thermal field. We propose a preliminary methodology for monitoring the temperature and humidity of the soil mass under the influence of heat-conveying communications. Among these communications there are heating, water mains, hot water supply and sewerage.The location of the communications in the near-surface soil mass and the presence of sufficiently high temperature loads from mains are taken into account. To date there is no information on the monitoring of the nature of the distribution of the soils temperature field in urban areas and, accordingly, the spatial variability of the physical and mechanical properties of soils under natural conditions.The reason for it is in short term of geotechnical investigations for specified objects on the stage of project documentation development. Also in the conditions of a city it's almost impossible to place an experimental site with expensive facilities — wells and equipment and provide its safety for a long time (at last 1 year or more).The paper describes the laboratory setup and principles of equipment monitoring systems in field conditions, the basic principles of the experimental work techniques. The theoretical generalization of the results of methodological experiments and conduct large-scale field experiments is a challenge for further research.
