1. A composite wall panel comprising:

  • a central body, substantially parallelepipedic in shape, comprised of an expanded polymer matrix, having opposite faces, a top surface, an opposing bottom surface, a male end and a female end; and

    two or more reinforcing embedded members transversely extending across the central body between said opposite faces, having a central portion embedded in the expanded polymer matrix, a first exposed end extending from the central portion and the top surface, and a second exposed end extending from the central portion and the bottom surface,wherein the reinforcing embedded members include one or more expansion holes located in the central portion of the embedded members and one or more utility holes located in the first exposed end and the second exposed end;

    a first concrete layer placed over the top surface encasing the first exposed end of the reinforcing embedded members; and

    a second concrete layer placed over the bottom surface encasing the second exposed end of the reinforcing embedded members;

    wherein the central body comprises a polymer matrix that expands through the expansion holes;

    wherein the set and hardened concrete of the first concrete layer fuses through the utility holes in the first exposed end;

    wherein the set and hardened concrete of the second concrete layer fuses through the utility holes in the second exposed end; and

    wherein the reinforcing embedded members comprise an epoxy resin reinforced with one or more fibers selected from the group consisting of carbon fibers, aramid fibers, glass fibers, metal fibers, and combinations thereof.
