PURPOSE:To provide the solidifying mixture by which the soft soil is improved, provided with good water permeability and strength and further rapidly solidified. CONSTITUTION:This mixture consists of an inorg. accelerating agent, a water- absorptive high molecular substance, quick lime and a cement-base solidifying material. The accelerating agent is sodium silicate, potassium silicate, sodium aluminate or sodium carbonate, the water-absorptive high molecular substance is natural polymer, synthetic polymer or their mixture, and the cement-base solidifying material is a mixture of cement and blast-furnace slag, slaked lime or gypsum. In this case, 3-100 pts.wt. of the inorg. accelerating agent is used with 100 pts.wt. of the solidifying material, and 0.1-10 pts.wt. of the water- absorptive high molecular substance is used with 100 pts.wt. of the solidifying material. |
