PROBLEM TO BE SOLVED: To provide a method for curing concrete on site whereby curing of concrete directly placed into forms at the site of civil engineering work or construction work can be effectively promoted to allow a reduction in period of construction. SOLUTION: When concrete 10' is placed into forms 20, 25 installed, the forms 20, 25 are entirely covered with a sheet 55, and steam is supplied from a boiler installed outside the sheet 55 into steam ejecting means 35, 35 installed within the sheet 55, to fill the inside of the sheet 55 with the steam. The quantity of steam supplied from the boiler is controlled by means of temperature sensors 40, 40 installed within the sheet 55, so that the temperature within the sheet 55 attains a predetermined value, to thereby promote curing.
