(57) [Abstract] [Purpose] Despite being a ground injection chemical, it has a wide range of gelation time, especially long gelation time, even though it is an inorganic chemical, Since it has a low viscosity, it has excellent penetrability and also improves the consolidation strength. [Structure] A water glass having a molar ratio in the range of 1.5 to 2.8, and fine particle slag having an average particle size of 10 μm or less and a specific surface area of 5000 cm 2 / g or more as active ingredients, Further, it is characterized by containing cement and / or limes, or, in addition, a calcium elution amount modifier, if necessary. |
