METHOD FOR MANUFACTURING CARBON DIOXIDE GAS FIXATION CONCRETE

Japanese Patent JP2023081065

A

To provide a method for manufacturing carbon dioxide gas fixation concrete which suppresses time constraint and place constraint for carbon dioxide gas fixation compared to a conventional method, and can increase an amount of carbon dioxide gas capable of being fixed.SOLUTION: A method for manufacturing carbon dioxide gas fixation concrete that is a method for manufacturing carbon dioxide gas fixation concrete in which a predetermined amount of carbon dioxide gas is fixed to concrete includes: a fresh concrete manufacturing step of manufacturing fresh concrete containing γ-C2S; a prior-to-placing carbon dioxide gas fixing step of supplying a carbon dioxide gas source to the fresh concrete manufactured in the fresh concrete manufacturing step and stirring the mixture, and obtaining carbon dioxide gas fixation fresh concrete in which the carbon dioxide gas is fixed to the fresh concrete; and a post-placing concrete curing step of placing the carbon dioxide gas fixation fresh concrete obtained in the prior-to-placing carbon dioxide gas fixing step and curing the carbon dioxide gas fixation fresh concrete, and obtaining carbon dioxide gas fixation concrete.SELECTED DRAWING: Figure 1
