PROBLEM TO BE SOLVED: To provide a method for manufacturing a concrete product capable of increasing absorption of carbon dioxide gas.SOLUTION: Porous concrete 3 is charged in a form 1, and carbon dioxide gas is absorbed into the porous concrete 3, thereby increasing carbon dioxide gas absorption of a wave block 12 as a whole. Carbonation is carried out by feeding a gas containing carbon dioxide into the form 1 through a supply tube 6 inserted from an aperture 1a of the form 1, thereby enabling the form 1 itself to serve as a shield and eliminating the need of establishing a curing tank as in conventional carbonation curing. Furthermore, a cement milk 11 is filled and solidified, thereby attaining quality equivalent to that of a normal dense concrete product. |
