Abstract
Fresh concrete is treated with carbon dioxide prior to delivery to a product mold for forming concrete products. Carbon dioxide gas is directed through a manifold, which may be coupled to a feedbox or a hopper, upstream from the product mold. Treating the fresh concrete with the carbon dioxide gas while it is in a loose state prior to placement in the product mold may generally promote uniform and enhanced carbon dioxide uptake.
Claims15
A method of retrofitting an existing apparatus for forming concrete products, wherein the apparatus comprises a component located upstream of a product mold and adapted to deliver concrete to the product mold, comprising adapting the component to treat fresh concrete to be delivered to the product mold by the component with carbon dioxide gas to form treated concrete, wherein the step of adapting comprises adding to the existing component a gas delivery system that is configured to direct the carbon dioxide gas onto a surface of the fresh concrete or at a stream of the fresh concrete, or any combination thereof, and wherein the gas delivery system is provided with one or more gas manifolds comprising a plurality of apertures, wherein the apertures are positioned to be in close proximity to the concrete but not in contact with the concrete, thereby retrofitting the existing apparatus into a retrofitted apparatus.
