Abstract
The article discusses one of the simplest and most effective methods of convective heating of concrete walls and columns in winter concreting conditions. The relevance of this issue is due to the need for high-quality heat treatment of concrete under specified heating conditions and reduction of energy costs due to the economical use of hot air generated in a closed heated space. The novelty of the presented method of heating concrete in winter concreting conditions lies in the simultaneous use of heating and fan devices, effectively installed in a rationally organized heated space. This ensures uniformity of temperature in height and in the volume of the heated space. The method of calculating the parameters of concrete retention of monolithic structures in winter conditions using convective heating, the principle of operation and the design feature of the device are given.
