Abstract: A concrete curing environment control sheet is provided to regulate the volume and temperature of a medium injected into a hollow formed in the curing sheet freely so as to control the concrete curing environment while minimizing damage of the sheet. A concrete curing environment control sheet is made up of a plurality of units(100) arranged side by side. The unit comprises a hollow pack(110) which is composed of upper and lower planes(111,112) and two lateral planes(113a,113b) and variable against compression and expansion, an upper wing(120a) which is protruded on the top of the hollow pack and attached to the top of the hollow pack of the adjacent unit, and a lower wing(120b) which is protruded on the bottom of the hollow pack and attached to the bottom of the hollow pack of the adjacent unit. A gap is formed between the upper wing and the lower wing of the adjacent units so that a medium is injected in the gap to control the concrete curing environment.
