To obtain a liquid admixture for ground stabilization, which carries out a pressure feed of constant delivery, provides a high viscosity reduction effect, uniformizes an injection substance, injects a cement milk to the ground under high pressure and hardens and stabilizes ground and a material for ground stabilization and to provide a construction method for ground stabilization.
The liquid admixture for ground stabilization comprises 100 parts wt. of a phosphate and 20-300 parts wt. of an alkali metal sulfate. The liquid admixture comprises further an organic acid. The liquid admixture has 10-50 parts wt. of a solid content in 100 parts wt. of the liquid admixture and pH 0.5-6. The material for ground stabilization comprises cement, the liquid admixture and water. The construction method for ground stabilization comprises injecting the material for ground stabilization into the ground under high pressure, mixing the material with soil and hardening the soil.
