摘要

PROBLEM TO BE SOLVED: To provide a curing material, a curing material solution, a chemical solution for soil stabilization, a method for producing the chemical solution, and a ground stabilizing method, which have a short gel time and excellent quick-setting property. A curing material used by mixing with a main material liquid containing lime and water to cure the main material liquid, such as dry aluminum hydroxide gel and alkali metal carbonate, or amorphous hydroxide. A curing material containing aluminum and alkali metal carbonate and alkali metal hydroxide and / or alkali metal silicate. A curing material liquid containing this curing material. A ground stabilization method in which a main material liquid containing lime and water and this hardened material are mixed in the ground. [Selection diagram] None
