Zusammenfassung:The invention discloses a pressure boosting control method for autoclaved aerated concrete, and belongs to the technical field of concrete product production. The method comprises the following steps: 1, setting pressure and temperature rise time, temperature rise acceleration range, steam curing initial temperature and constant temperature; 2, uniformly dividing the boosting and heating time into n time periods, taking a demarcation point of each time period as a time node, and calculating a heating base value; 3, calculating the temperature of each node; 4, according to the calculated temperature of each node, looking up a table to obtain corresponding node pressure, and then drawing a pressure rise curve graph; 5, calculating the enthalpy of the saturated water vapor required by each time period in the boosting process; and 6, calculating the saturated water vapor amount and the steam flow required by each time period, and controlling the pressure in the boosting process. According to the invention, the st
