<p><P>PROBLEM TO BE SOLVED: To provide a grouting method presenting flow characteristics and consolidation characteristics corresponding to various purposes by mixing various active components at a specific mixing ratio. <P>SOLUTION: Mixed liquid of fly ash F, cement C and water W used as active components at a cement ratio of 50 wt.% or less and a water-powder ratio of 30-130 wt.% is pressed into the ground. When the mixed liquid becomes gel in the ground, the mixed liquid is consolidated via a plastic state of flowing under the action of external force although it does not flow as it is. The mixed fluid of such constitution is pressed into the ground and consolidated pushing soil grains away to the periphery. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
