TECHNOLOGY OF WINTER CONCRETING OF MONOLITHIC CONSTRUCTIONS WITH APPLICATION OF HEATING CABLE

Antonina Yudina, Rafael Oganyan

Abstract


At the present time, the problem of structure concreting at negative temperatures is particularly sensitive. One of winter concreting methods is electrical heating of structures with the help of heating cable. The paper presents the analysis of existing studies of the concrete curing technology with electric cable upon winter concreting and criteria for selecting the equipment and materials for heating; organizational and technological diagrams were developed for winter concreting of structures with application of concrete heating with electric cable. Recommendations for the selection
of heating elements and wiring schemes are given, based on the requirements for improvement of work performance, optimization and rational use of labor and material resources, reduction of time for auxiliary works. Risks, associated with the winter concreting technology with the use of heating cable, were assessed within the framework of the paper.

Keywords
