Soil stabilization chemical solution, manufacturing method of the chemical solution, and ground stabilization method

摘要

PROBLEM TO BE SOLVED: To shorten a stirring time required for producing a main material liquid and a cured material liquid to obtain a stable gel time even when the gel time is set to 40 seconds to several tens of minutes, and the hardness of the chemical solution after gelation. Provided are a chemical solution for soil stabilization, a method for producing the chemical solution, and a ground stabilization method. SOLUTION: This is a soil stabilizing chemical solution obtained by combining the following main material liquid A and the following curing material liquid B, and is characterized by containing an organic carboxylic acid and / or a salt thereof. Main material liquid A: Water-hardening cement excluding alumina cement, lime, and main material liquid containing water Hardening material liquid B: One selected from the group consisting of alumina cement, inorganic carbonate, bentonite, sepiolite, and attapulsite. Hardener liquid containing the above clay minerals and water [selection diagram] None
