HEAT SHIELD CURING METHOD AND HEAT SHIELD CURING SHEET FOR COLD WEATHER CONCRETE

PROBLEM TO BE SOLVED: To provide a heat shield curing method for cold weather concrete, allowing for heat insulation curing with high heat shield effect without heat supply, which blocks flow from outside cold air to cold weather concrete and prevents heat transfer toward ambient air so that the cold weather concrete can be cured with hydration heat of concrete in a formwork; and a heat shield curing sheet for cold weather concrete.SOLUTION: In a method for curing cold weather concrete, the surface of a formwork 3 disposed on the surface of installed concrete 2 is covered with a heat shield curing sheet 1 composed of a foam plastic sheet 11 having at least an inner air layer 11a which is integrally held between metal thin film layers 12 and 12 at both sides, so that radiation of hydration heat of the concrete 2 is reduced and outside cold air is blocked.
