PROBLEM TO BE SOLVED: To provide an improved grout and a method for solidifying ground in terms of ease of construction and ground improvement effect in addition to cost and environmental load reduction. The grout according to the present invention comprises an amino acid, a calcium salt, and phosphoric acid and / or phosphate that are metabolized and decomposed by microorganisms in the ground to generate ammonia. According to the method for consolidating the grout and the ground according to the present invention, the speed at which the ground consolidates can be adjusted. For example, the grout can be prevented from solidifying during the injection, and the ground can be made uniform. It is possible to easily adjust the time required for solidification or ground consolidation. [Selection] Figure 9 |
