PROBLEM TO BE SOLVED: To provide a concrete curing form which enables water to be directly and uniformly supplied onto the surface of the concrete. SOLUTION: This concrete curing form 1 includes a form body 2, a water-retaining portion 3 which covers the inside surface of the form body 2, and a surface portion 4 which covers the inside surface of the water-retaining portion 3 and which faces concrete C placed in the form. The water-retaining portion 3 is made of a water-permeable material with strength high enough to prevent deformation caused under the pressure of the concrete C. The surface portion 4 is made of a sheet-like material which can permit the passage of moisture and inhibit the passage of cement particles. COPYRIGHT: (C)2010,JPO&INPIT |
