Panel material for concrete curing form and concrete curing method

摘要

PROBLEM TO BE SOLVED: To provide a concrete curing form and a concrete curing method capable of suppressing the temperature difference between an inside part and a surface of concrete, preventing dissipation of moisture from the inside of concrete, and improving concrete strength.SOLUTION: A concrete curing form 2 is used for regulating a concrete filling space 3 to be filled with fresh concrete c and holding and curing the concrete c filling the concrete filling space 3. A panel material 1 used as a panel material for configuring the concrete curing form 2 is comprised of: a liquid-permeable sheet 5 made of a porous material; an inner surface plate 11 which is arranged on the side of the concrete filling space 3 and of which surface 6 is joined with the liquid-permeable sheet 5; a non-porous outer surface plate 12 joined in parallel to the inner surface plate 11 with an interval; and a plate-shaped auxiliary member 9 made of a material having a lower elasticity in the thickness direction thereof than that in the thickness direction of the inner surface plate 11 and the outer surface plate 12, and joined to a surface 8 on the opposite side to the side, to which the liquid-permeable sheet 5 is joined, of the outer surface plate 12.
