1. Способ управления процессом тепловой обработки бетонной смеси в термоактивных опалубках, включающий нагрев уложенной смеси путем подачи теплоносителя, измерение температуры смеси, ограничение температуры ее поверхностного слоя путем изменения подачи теплоносителя в процессе тепловой обработки, выдерживание бетона до набора требуемой прочности, отличающийся тем, что измеряют температуру наружного воздуха и скорость ветра, учитывают вид бетонируемого сооружения, конструктивные особенности термоактивной опалубки, вид уложенной бетонной смеси, и определяют время набора бетоном заданной прочности, время подъема температуры до величины изотермического прогрева и время остывания бетона согласно приведенным зависимостям.1. The method of controlling the process of heat treatment of concrete mixture in thermosetting formwork, including heating the laid mixture by supplying a coolant, measuring the temperature of the mixture, limiting the temperature of its surface layer by changing the flow of coolant in the process of heat treatment, keeping the concrete to the set strength required, characterized in that measure the outdoor temperature and wind speed, take into account the type of concrete structure, design features of thermoactive formwork, type of laid onnoy mixture, and determine when the concrete sets the desired strength, while a temperature rise to a value of isothermal heating and cooling time of concrete according to the given formula. 2. Способ по п.1, отличающийся тем, что момент прекращения подачи теплоносителя определяют по истечении времени изотермического прогрева бетона.2. The method according to claim 1, characterized in that the moment of termination of the flow of coolant is determined after the time of isothermal heating of the concrete.
