Abstract
A method and apparatus for rapidly manufacturing concrete or like products having an advanced state of cure by blending together a calcareous cementitious binder, aggregate, and water to form a mix, molding the mixture to have a predetermined shape and exposing the shape to an atmosphere in a chamber consisting essentially of carbon dioxide gas, wherein carbon dioxide gas is fed under controlled conditions into said chamber through a series of tubes having a multiplicity of spaced orifices during the movement of the shape therein and continuing the feed so as to cause an exothermic temperature rise in the shape.
