Descrição: The purpose of the present work is the search of the rational mode of thermal treatment of high-performance self-stressing self-compacting concrete. At the present time, only few of such investigations have been carried out by scientists. In the present paper, the results of scientific tests implemented by the authors for holding temperature 50°C and 60°C are outlined. Dependence between relative strength of concrete specimen cylindrical form and the total time of electrical curing at fixed duration of temperature rise and cooling has been figured out. The scientific experiments implemented have shown that the mode of thermal treatment 3 + 5 + 3 of high-performance self-stressing self-compacting concrete with the temperature of isothermal time 60°C allowed obtaining the value of relative strength at axial compression of 70%. Along with that, strength of concrete at 28 days corresponded to the concrete grade B80. The obtained data can be used to verify results of calculations.
