PURPOSE: To make concrete in a form dry.
CONSTITUTION: A form 14 supporting concrete 11 is formed of reinforcements 18 to be arranged in the concrete 11 and dead forms 12 surrounding the concrete 11. Pores 15 are provided to a bottom plate 16 of the dead form 12, and the surface of the concrete 11 is finished with a finishing material (by coating or sticking). Since the pores are provided to the form, the concrete in the form is dried, and application of the finishing material can be made without regard to moisture in the concrete, resulting in shortening of term of work for applying the finishing material to the concrete. This further results in shortening of term of work for constructing a concrete slab equipped with a perforated steel plate.
