Abstract: PURPOSE:To improve the crack prevention, warpage prevention, water repellency and strength of a cured hydraulic substance by curing the hydraulic substance, while spraying steam having a temperature lower than room temperature during the prescribed curing of the hydraulic substance for the supply of insufficient water. CONSTITUTION:A hydraulic substance (A) such as mortar is cured, while a temperature gradient between the temperature of the atmosphere and the temperature of the component A is reduced or while the temperatures are controlled substantially to the same temperature. The cured product (B) is subjected to both the above-mentioned curing process and a curing process preventing the dropping of dew drops from the ceiling of a curing chamber or a curing process preventing the generation of dew drops on the ceiling and/or wall of the curing chamber to obtain the cured product (C). When the cured product A or B is produced, the component A or B is treated under a high moisture condition or under a high moisture and a high pressure, while the pressure gradient between the outer and inner pressures of the mortar, etc., is reduced so as to control both the pressures substantially to the same pressure, thus producing the cured product (C) of the hydraulic substance wherein dew condensation on the exposed surfaces of the cured product is prevented. The cured product C is disposed in a high moisture curing chamber, if necessary, equipped with a water tank. etc., and subsequently cured with the supply of fine water drops by the use of an ultrasonic humidifier, etc., to produce the highly strong cured product of the hydraulic substance.
