PROBLEM TO BE SOLVED: To provide a concrete curing method in which a curing sheet is fitted on an inner surface of a sheathing board so the sheet does not peel off from the sheathing board before or during casting and remains on the concrete side when removing the mold.SOLUTION: In a concrete curing method of the present invention, a curing sheet 5 is placed in advance on an inner surface 4 of a sheathing board 1 that comprises a mold 3, and concrete is cast in a casting area inside the mold while the mold 3 is in an assembled state, and then the mold 3 is removed after the concrete attains the prescribed strength, in such a way to have the curing sheet 5 remain on the concrete side. When placing the curing sheet 5, decompression is carried out through an open hole 6 drilled through the sheathing board after placing the curing sheet 5 in advance on the inner surface 4 of the sheathing board 1. The decompressed state is maintained at least until the concrete casting is complete, and the decompressed state is released before removing the mold 3. |
