PROBLEM TO BE SOLVED: To provide equipment for curing a concrete formed body under high-temperature and high-pressure water, which is excellent in safety, energy efficiency and production efficiency by reutilizing curing water. SOLUTION: This equipment has plural pressure vessels 4A and 4B, each of which is provided with a curing water supply means 6 for supplying water to the inside, a compressed air supply means 8 for supplying compressed air to the inside, a heater 12 for heating the supplied water and an evacuation means 10 for evacuating the inside so as to attain a reduced pressure, and transfer lines 16A and 16B for high-temperature and high-pressure water, each of which is placed below the corresponding one of the pressure vessels 4A and 4B and connected to the other pressure vessel 4B or 4A at its optional position and communicated with it through the corresponding one of open-close valves 14A and 14B, so that the pressure vessels 4A and 4B are connected to each other by the transfer lines 16A and 16B in such a way as to form a circulation passage through the pressure vessels 4A and 4B. Thus, the curing water just after completing the curing in one of the pressure vessel 4A and 4B, is not discarded but successively transferred by utilizing a high pressure within the pressure vessel 4A or 4B to the other pressure vessel 4B or 4A being on standby under the atmospheric pressure, through the corresponding one of the transfer lines 16A and 16B, to repeatedly utilize the curing water.
