PURPOSE: To omit the trouble of operation, and to enable the execution of works in a short period by projecting and forming a plurality of projections, which are stuck detachably onto the surface of forms and in which diameters are expanded toward the concrete-placing surface side, from a curing sheet.
CONSTITUTION: Concrete C is placid into forms 2 under the state, in which a curing sheet 1 is stuck on the form surface of forms 2, and the curing sheet 1 is left on the surface of a concrete structure under the state, in which the projecting sections 3 of the curing sheet 1 are bitten to the surface of concrete C, when the forms 2 are removed after concrete C is solidified. When the curing sheet 1 is pulled forcibly from the surface of concrete C after curing is completed, the curing sheet 1 is peeled off from the surface of concrete C while the projecting sections 3 are distorted elastically or the roots of the projecting sections 3 are cut, thus removing the curing sheet 1. Accordingly, forms can be taken off at an early stage after concrete is placed.
