Composite insulated plywood, insulated plywood concrete form and method of curing concrete using same
First Claim
1. A product comprising:
- an insulated, removable concrete form for substantially retaining the heat of hydration of hydraulic cement comprising;
a first concrete forming panel of wood or plywood having a first primary surface adapted for forming and contacting plastic concrete and releasing hardened concrete and a second primary surface opposite the first primary surface, wherein the first concrete forming panel defines a plane;
a concrete release coating on the first primary surface of the first concrete forming 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 contacting the second primary surface of the first concrete forming panel and the second primary surface of the second panel, the layer of insulating material substantially covering the second primary surface of the first concrete forming panel, 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, the frame providing sufficient reinforcement to the first concrete forming panel such that the first concrete forming panel withstands the hydrostatic pressure of plastic concrete contacting the first primary surface, wherein no portion of the concrete form frame is in the plane defined by the first concrete forming panel;
a quantity of plastic concrete contacting the first primary surface of the first concrete forming 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.

Abstract
The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface; and a second panel having a first primary surface and a second primary surface opposite the first surface, the second panel being attached to the first panel so that the first primary surface of the second panel is adjacent the second primary surface of the first panel. The concrete form also comprises a layer of radiant heat reflective material and a layer of insulating material disposed between and covering the second primary surface of the first panel and first primary surface of the second panel. A method of using the concrete form is also disclosed.
