(57) [Summary] [Purpose] Good water permeability is obtained for the improvement of soft soil properties, and the strength is large and it is possible to solidify more rapidly. [Structure] The solidifying mixture of the present invention comprises an inorganic quick-setting agent, a water-absorbing polymer substance, quicklime and a cement-based hardening agent, and the inorganic quick-setting agent is sodium silicate, potassium silicate, sodium aluminate or sodium carbonate. The water-absorbing polymer substance is a natural polymer, a synthetic polymer, or a mixture thereof, and the cement-based solidifying material is a mixture of cement and blast furnace slag, slaked lime, or gypsum. The inorganic salt quick-setting agent is 3 to 100 parts by weight with respect to 100 parts by weight of the cement-based solidifying material, and the water-absorbing polymer substance is 0.1 parts by weight to 100 parts by weight of the cement-based solidifying material. 10 parts by weight. |
