Composite insulated plywood, insulated plywood concrete form and method of curing concrete using same

A product comprising:

• an insulated, removable concrete form for substantially retaining the heat of hydration of hydraulic cement comprising:
• a first panel of wood or plywood having a first primary surface and a second primary surface opposite the first primary surface, wherein the first panel defines a plane;
• a concrete release coating on the first primary surface of the first panel;
• a second panel having a first primary surface and a second primary surface opposite the first primary surface;
• a continuous layer of insulating material disposed between the second primary surface of the first panel and the second primary surface of the second panel, the layer of insulating material substantially covering the second primary surface of the first panel, the second primary surface of the first panel and the second primary surface of the second panel facing the layer of insulating material, wherein the layer of insulating material has an R-value of greater than 8;
• and
• a concrete form frame disposed on and contacting the first primary surface of the second panel, the concrete form frame comprising a plurality of bracing members oriented transversely with respect to the first primary surface of the second panel, wherein no portion of the concrete form frame is in the plane defined by the first panel;
• a quantity of plastic concrete contacting the first primary surface of the first panel;
• and
• wherein the insulated, removable concrete form is removable from the quantity of plastic concrete after the quantity of plastic concrete has cured to a desired degree.
