CALCULATION OF THE PARAMETERS FOR HEAT TREATMENT OF CONCRETE WITH AIR CONVECTIVE HEATING OF THIN-WALLED MONOLITHIC STRUCTURES

Abstract

The article discusses one of the simplest and most effective methods of heat treatment of con-crete 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 speci-fied curing time and in the reduction in energy costs by increasing the efficiency of the use of ther-mal 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 pa-rameters of concrete curing of thin-walled monolithic structures in winter conditions using convec-tion heating and the basic principles of selecting heat generators are presented.
