    b) a conveyor belt means having a receiving end and a discharge end, said conveyor belt means being disposed beneath said storage compartment in sufficient proximity to the outlet portion of the storage compartment to receive a quantity of said concrete precursor, with the concrete precursor comprising a portion that contacts the conveyor belt means and a top surface portion;

    c) at least one adjustable gate means disposed along the travel path of said conveyor in a position that is above the conveyor belt and in contact with the top surface of said quantity of said concrete precursor;

    d) a cement powder storage compartment having an outlet, wherein said outlet is disposed in sufficient proximity to deliver a quantity of cement powder to the top surface of said concrete precursor as it travels along said conveyor, wherein said outlet of said cement powder storage compartment includes an airlock rotary vane feeder, e) an auger inlet chamber having a bottom portion and disposed at the delivery end of said conveyor belt means, which inlet chamber is adapted to receive the cement powder and concrete precursor from the delivery end of the conveyor belt means, wherein said auger inlet chamber includes a means for adding a desired quantity of water to said cement powder and concrete precursor which enters said inlet chamber; and

    f) a screw auger having an inlet end and an outlet end, wherein said inlet end is disposed in the bottom of said auger inlet chamber and is adapted to receive said cement powder, concrete precursor, and water, from which fresh concrete may be caused to emerge from said outlet end of said screw auger during its rotation.
