<P>PROBLEM TO BE SOLVED: To provide a solidification material for soil improvement, which is excellent in workability and is capable of sufficiently improving soil. <P>SOLUTION: A solidification material for soil improvement contains cement, blast furnace slag powder, aggregate and gypsum, and for the total of 100 pts.mass of the cement, the blast furnace slag powder, the aggregate and the gypsum, contains 50 to 75 pts.mass of the cement, 15 to 35 pts.mass of the blast furnace slag powder, 1 to 15 pts.mass of the aggregate and 1 to 15 pts.mass of the gypsum. Slurry 30 for the soil improvement contains the solidification material for the soil improvement and water, and for 100 pts.mass of the solidification material for the soil improvement, contains 10 to 65 pts.mass of the water. In a kneading process, the slurry 30 for the soil improvement and a part of the soil of the ground 20 at the lower part are kneaded to obtain a kneaded object 50. The kneaded object 50 is hardened and turned to improved soil, and the ground 20 is improved. Since the improved soil obtained in such a manner is improved using the slurry 30 for the soil improvement, it has high strength and the dispersion of ground strength is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
