ANALYSIS OF CONSTRUCTION WORKS IN WINTER TIME
The article presents the analysis of technologies of winter concreting, presents the results of research and calculations application of heated concrete mixes to increase the quality of construction works. Presents evaluation of different methods for heating concrete mixtures, the advantages and disadvantages of each method. As a result of research, it was determined that heating by the method of resistive heating (thermosetting) of the formwork systems winter concreting has significant economic efficiency, the consumption of heating elements of electricity by more than 30?% less than other types of electric heating. In a result of the done work it was shown that the introduction of new types of heating elements will help to increase not only the quality of work on winter concreting, but also significantly reduce the economic costs. Research and calculations showed that the heating by using the thermosetting formwork is economically attractive for use in construction companies with mass building in the climatic conditions which prevail negative temperature.
