Title:
CARBON DIOXIDE IMMOBILIZATION METHOD AND CURED CEMENT BODY FOR CARBON DIOXIDE IMMOBILIZATION
Document Type and Number:
WIPO Patent Application WO/2023/176969
Kind Code:
A1
Abstract:
In this carbon dioxide immobilization method, a cured cement body (10) is impregnated with a carbon-dioxide-absorbing liquid containing a carbon dioxide absorbent (20) in order to support the carbon dioxide absorbent (20) on the cured cement body (10) and obtain a cured cement body (1) for carbon dioxide immobilization; and the cured cement body (1) for carbon dioxide immobilization is brought into contact with the atmosphere and the carbon dioxide contained in the atmosphere is immobilized in the cured cement body (1) for carbon dioxide immobilization.
