| titleOfInvention | Ground improvement method |
| abstract | Provided is a ground improvement method capable of enhancing the compressive strength of soil cement even in the case where an acidic soil containing an organic substance such as a humic acid, a fulvic acid, a humin, or a bitumen is used. This ground improvement method comprises steps 1-3. <Step 1> A step for formulating a slurry by mixing water, a hydraulic powder, and a component (A). Component (A): A particle group having a particle size of 30 nm or less, 70 nm or less, and 100 nm or less when the respective cumulative number frequencies are 10%, 50%, and 90%, respectively, as determined by measuring the particle sizes of all contained particles by dynamic light scattering and plotting cumulative number frequencies with respect to particle size. <Step 2> A step for injecting the slurry obtained in step 1 into a ground to mix the slurry with a soil to obtain a mixture, wherein the mixed amount of the slurry per 1 m3 of the soil is 150-800 kg, and the mass ratio of the hydraulic powder and the soil in the mixture is 0.01-0.6. <Step 3> A step for solidifying the mixture of the slurry and the soil obtained in step 2. |
