Title:
CURING SHEET OF CONCRETE STRUCTURE AND MANUFACTURING METHOD OF CONCRETE STRUCTURE USING THE SAME
Document Type and Number:
Japanese Patent JP2017020250
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a curing sheet of the concrete structure stuck on a form inner surface and used in a manufacturing method of the concrete structure for removing a formwork and performing curing during a predetermined period so as to be left in the concrete structure side after concrete placement, the curing sheet that facilitates removal of the formwork so as to be left in the concrete structure side in the formwork removal, highly adheres to the concrete structure and can inhibit bleeding water, and as a result, has high strength of the concrete surface and can manufacture the concrete structure without pockmarks on the concrete surface.SOLUTION: A curing sheet of a concrete structure is characterized in that the curing sheet is formed by stacking a slightly adhesive layer on one side of a non-permeable base material comprising a polypropylene-based resin or a polyethylene terephthalate-based resin, and is stuck on a form inner surface, and the adhesive power with the form inner surface when placing concrete is smaller than the adhesive power with the concrete structure.SELECTED DRAWING: Figure 1
