Calculation of the parameters for heat treatment of concrete with air convective heating of thin-walled monolithic structures

The article discusses one of the simplest and most effective methods of heat treatment of concrete walls and floors erected in tunnel form - the convection heating method. The relevance of this issue lies in the need for high-quality heat treatment of concrete of thin-walled structures at a specified curing time and in the reduction in energy costs by increasing the efficiency of the use of thermal energy. The types of the convection heating method are classified according to the principle of bringing the heat flow to the heated structure: “traditional” chamber heating, “chamber heating with air ducts”, and “convection heating with pre-formwork curtains”. The method for calculating the parameters of concrete curing of thin-walled monolithic structures in winter conditions using convection heating and the basic principles of selecting heat generators are presented.
