い。2. Description of the Related Art In order to improve the quality of concrete and to provide required strength and durability as a structural material,
It is important to provide sufficient curing during construction. The longer the period of concrete curing, the higher the strength, durability and watertightness. In particular, it is necessary to sufficiently protect concrete against temperature changes such as insolation in the heat and low temperature in the middle of the cold and drying, and it is desirable not to remove the formwork used during casting as long as possible.

型枠を取り外した後に、養生を続行するために別途養生
工として、養生作業を組み入れていた。However, when casting concrete using a formwork, there is a tendency to remove the formwork as early as possible from the viewpoint of work process restrictions and construction period. If the mold is removed early, the concrete will be directly exposed to the atmosphere, and its quality will deteriorate due to temperature changes and drying. So, conventionally,
After the mold was removed, curing work was incorporated as a separate curing mechanic to continue curing.
【０００４】しかしながら、このような従来の養生方法

A method for curing concrete in which the curing sheet is left in a state of being adhered to the surface of the concrete after removal, wherein the curing sheet has a heat insulating member disposed at the center and both surfaces of the heat insulating member sandwiching the heat insulating member. Bei the adhesive film of the pair of impermeable adhered arranged
Attaching one of the adhesive films to the formwork with an adhesive, and applying an alkali-resistant adhesive capable of adhering to the concrete to be cast on the outer surface of the other film, And the formwork
The adhesive strength of the adhesive to be applied is determined by the adhesion of the alkali-resistant adhesive.
I made it weaker than my strength . According to the curing method having the above configuration, after removing the mold, the curing sheet is left in a state of being adhered to the surface of the concrete, and further, the curing sheet is provided with a heat insulating member disposed at the center and the heat insulating member. Since it has a pair of water-impermeable adhesive films disposed on both sides so as to sandwich it, concrete is shielded from temperature changes such as solar radiation in the hot summer and low temperature in the middle of the cold and prevents drying. Thus, the wet state can be maintained.
