<p><P>PROBLEM TO BE SOLVED: To enable neutralization, by enhancing denseness of a structure formed in the ground without sacrificing workability, when improving the ground in an original position by a mechanical agitating method or a high pressure injection method, by using a cement-based material. <P>SOLUTION: A ground improvement construction method agitates and mixes the cement-based material with earth of the object ground by the mechanical agitating method or an injection agitating method. This carbonated ground improvement construction method injects a CO<SB>2</SB>source into its processing part via an injection pipe, before completing hardening, after forming a skeleton in the mixing processing part, by blending aγbelite with the cement-based material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
