The lightweight concrete panel is comprised of a thin concrete slab, a standard steel stud frame, optional insulation strips to increase its thermal performance for exterior wall applications, and specially engineered rivets or screws that connect the thin concrete slab to the metal frame. The specially engineered rivet has a protruding and shaped head that acts as an anchor when embedded in the hardened concrete slab and has an optional elastic cover in its embedded head to allow slight movement of the concrete slab.
