CARBON DIOXIDE TREATMENT OF CONCRETE UPSTREAM FROM PRODUCT MOLD

摘要

WSGR Docket No. 44131-705601 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.
