<P>PROBLEM TO BE SOLVED: To provide an air layer forming sheet which can be used by being attached to a surface of concrete for instance as a curing sheet, and a concrete curing method using it. <P>SOLUTION: For the air layer forming sheet of this invention, an adhesive 3 (acrylic adhesive to which a polyepoxide compound based crosslinking agent is added and mixed) is applied to the surface of a sheet body 2 having an air layer 2c. The amount of the polyepoxide compound base crosslinking agent added and mixed in the acrylic adhesive is 1.0 to 2.5 pts.mass to 100 pts.mass of the acrylic adhesive. The surface of the sheet body is formed by a plastic film 2a, and corona treatment is executed to the surface where the acrylic adhesive is to be applied. In the concrete curing method of this invention, by attaching the air layer forming sheet to the surface of the concrete immediately after detaching a mold form as a curing sheet, the concrete is cured. <P>COPYRIGHT: (C)2012,JPO&INPIT |
