1. A lightweight multilayer heat reflective concrete cure blanket comprising:

  • a moisture impervious first top outer layer;

    a moisture impervious second bottom outer layer disposed in spaced relation to said first top layer, said first and second layers sealingly connected to each other at the boundaries of said layers to form a moisture-impervious chamber between said first and second layers;

    at least one heat insulative layer disposed in said chamber between said first and second layers; and

    said second bottom layer comprising a woven material having an upper and lower surface, a heat reflective material applied to the lower surface of said woven material to reflect heat emanating from the concrete when the blanket is placed over concrete, and a protective heat permeable layer over said heat reflective material to protect the heat reflective material from chemicals and dirt in the concrete.
