METHOD AND DEVICE FOR FIXING CARBON DIOXIDE

Document Type and Number:

WIPO Patent Application WO/2024/090269

Kind Code:

A1

Abstract:

[Problem] To provide a method for fixing carbon dioxide with which carbon dioxide can be efficiently fixed in the ground during ground improvement using cement slurry. [Solution] When cement-improved piles are created by pumping and stirring cement slurry into the ground, carbon dioxide is pumped directly into the ground, where the carbon dioxide is dissolved in pore water and mixed with cement slurry, thereby generating calcium carbonate. Therefore, carbon dioxide can be efficiently fixed in the ground.
