摘要： A mold assembly for making concrete blocks includes a billet of foamed polystyrene having flat upper and lower surfaces, and having apertures produced by a CNC milling machine. The apertures are bounded by perimeter walls of varied contour orthogonally disposed to the flat surfaces of the billet. The bottom surface of the billet is secured to a flat rigid floor panel. Blocks are produced by pouring concrete into the aperture, allowing the concrete to harden, then breaking the polystyrene away from the blocks formed within the apertures.
