ABSTRACT:
A method of casting concrete blocks having a fractured face. A pattern or frame is embedded in a mass of concrete within a mold and after the mass is compacted within the mold and about the frame, the frame is moved relative to the compacted mass so as to randomly fracture the concrete mass between the elements of the frame. The frame together with a portion of the fractured mass are removed from the finished block.
