Document Type and Number:
Japanese Patent JP6788645
Kind Code:
B2
Abstract:
To provide a production method of a solidification material for soil improvement, which generates little dust, has good storage stability, can decrease elution of pollutant, and has excellent stability of an aqueous solution in the production process.SOLUTION: The production method of a solidification material comprises a step of mixing: an aqueous solution containing a compound (a) selected from hydroxymethanesulfonic acid (salt) and hydroxymethanesulfinic acid (salt) in an amount of 0.01 to 1.0 pt.mass relative to 100 pts.mass of cement, a compound (b) selected from an ethylene oxide adduct of methanol and polyethylene glycol, a compound (c) selected from glycerin and diethylene glycol in a total amount of 72 mass% to 85 mass%; and cement. In addition, pH of the aqueous solution is 4.0 to 8.0; a mass ratio of compound (c)/compound (b) is 0/100 to 70/30; and, relative to 100 pts.mass of the cement, a total of compounds (b) and (c) is 1.0 pts.mass to 7.0 pts.mass and an amount of water is 0.3 pts.mass to 2.0 pts.mass.SELECTED DRAWING: None
