Abstract
Currently, there is a significant increase in personal and commercial road transport in the Russian Federation, which is why the issue of building new roads, bridges, tunnels, and other crossings is becoming more acute. Since often during the construction of these facilities, one of the main tasks is to minimize the construction period of the object, the process of intensifying production processes comes first. Based on the fact that the absolute leader in the use of reinforced concrete as the main building material, it is important and necessary to observe all the quality characteristics of this material both at the stage of laying the concrete mixture in the formwork, and in the process of maintaining the hardening concrete until the termination of heat-and-humidity care for it. In this regard, in order to optimize the temperature factor of hardening concrete in the construction of transport infrastructure facilities, it is necessary to provide measures at the design stage to consider the influence of the temperature gradient of hardening concrete on the operational properties of building structures. The article presents the main methods for considering the temperature factor of the hardening concrete of the constructed structures, developed by the authors of the work, the use of which will ensure the defect-free concreting of objects, including in an accelerated time.
Highlights
The modern world is difficult to imagine without road and rail transport
In the Russian Federation, a number of major facilities have been built in recent decades, including the bridge on Russky Island, the Crimean Bridge, the Olympic facilities in Sochi, large construction sites in Moscow, St
The current experience in the construction of transport facilities for various purposes shows that to account for and control the temperature factor of hardening concrete, there are quite a lot of different methods aimed at obtaining structures of the required quality [1 ... 4]
Summary
The modern world is difficult to imagine without road and rail transport. New roads, bridges, overpasses, and interchanges are being built everywhere. The key is to observe requirements for ensuring the high-performance properties of structures in connection with which the fore the issue of accounting for temperature factor of hardening of concrete during the construction of transport infrastructure in an accelerated time frame.
