1. A concrete casting table comprising:
- a first horizontal concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface, wherein the first concrete forming panel defines a plane;
a second horizontal 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 panel;
a plurality of vertical side members, each of which has a first primary surface adapted for forming plastic concrete and a second primary surface opposite the first primary surface, wherein the first horizontal concrete forming panel and the plurality of vertical side members define a concrete mold cavity;
a continuous layer of insulating material substantially covering the second primary surface of each of the plurality of side panels; and
a frame disposed on 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 concrete forming panel.

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, wherein the first panel is made from a rigid plastic sheet or a metal sheet; and a second panel spaced from the second primary surface of the first panel, wherein the second panel is made from a rigid plastic sheet or a metal sheet. The concrete form also comprises a layer of insulating material disposed between the first panel and the second panel. A method of using the concrete form is also disclosed.

14. A method of forming concrete comprising:
-
placing plastic concrete in a concrete mold defined by a plurality of mold forming members, each of which has a first concrete forming surface and an opposite second surface, the second surface of each of the plurality of mold-forming members being substantially covered by a layer of insulating material such that the plurality of mold-forming members are thermally isolated from the surroundings; placing plastic concrete in the concrete mold, the plastic concrete having an exposed surface; placing a layer of insulating material over the exposed surface of the plastic concrete; and leaving the plastic concrete in the concrete mold for a time sufficient to at least partially cure the plastic concrete.
