METHOD FOR MANUFACTURING CONCRETE PRODUCT

摘要

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 placed inside a concrete layer 2, thereby enabling carbon dioxide gas to be absorbed into a carbonated part 13 and increasing carbon dioxide gas absorption of a concrete block 12 as a whole. An outer periphery of the carbonated part 13 is covered with the concrete layer 2 so as not to expose the porous concrete 3 and to maintain a fine appearance as a concrete product. A cement milk 11 is filled and solidified in a gap inside the carbonated part 13, thereby attaining quality equivalent to that of a normal dense concrete block.
