Optimization of concrete works technological process in the winter period

Abstract

The goal of this study was to optimize the technological process of works related to concreting in the winter period to ensure a high-quality overhaul process. Demonstrate by laboratory research the effect of using various methods of concreting on the quality of work performed. To study thermodynamic processes, a stand is used that monitors the temperature fields in the volume of the concrete mixture, as well as heating elements with a positive coefficient of thermal resistance. The distribution of temperature fields in the volume of concrete mixture was studied depending on applied methods of concreting. Studies have shown that in order to reduce the time of repair work in the winter period, it is necessary to heat up the base of structures, and apply additional heating for critical structures. The experiments have shown that the use of heating elements with a positive coefficient of resistance when carrying out concrete work in the winter period of time will provide a high-quality performance of repair and construction work.
