Abstract
The present paper considers the features of construction at low temperatures and introduces the previous studies on improving the reliability of metal and reinforced concrete structures. Low temperatures adversely affect penetration of the edges of metal products during welding. Notably, design engineers consider the results of investigations and calculations, and incorporate steel products made of lowalloy, stainless steels, and nickel alloys. These materials demonstrate high viscosity, good weldability, retain strength in the process of manufacturing structures and their operation. The paper analyzes the construction works in winter conditions and considers installation as one of the main technological processes in construction. In addition, the paper lists the restrictions for welding and concreting, as well as indicates the conditions for structures to be installed using bolts or manual arc welding. Manufacturing plants are known to treat metal products and structures with protective coatings prior to transportation to the construction site. These technological operations are aimed at protecting metal from corrosion and at retaining heat within buildings. All winter concreting techniques are indicated to be implemented on the construction site at temperatures below 5°C. Gaining the required strength of the cement needs more time in cold temperatures than at a temperature of +20°C. The method of artificial heating, presented in the paper, is intended to create durable concrete and reinforced concrete products and structures.
