PURPOSE:To shorten the time for preparing a soil stabilizer, by a method wherein as components of a soil stabilizer, an aq. soln. of sodium silicate and another aq. soln. component contg. sodium hydrogensulfate together with potassium chloride are separately prepd., and both soln. are mixed together when applied. CONSTITUTION:Before applying, the following liquids A and B are separately prepd. When applied, both liquids are mixed together, and injected into a soil to cause the mixed liquid to gel in the soil, whereby the soil is stabilized. When the above liquid B for use in the above method is prepd., potassium chloride is used together with sodium hydrogensulfate. The above liquid A consists of an aq. soln. of sodium silicate. The above liquid B consists of an aq. soln. of sodium hydrogensulfate alone, or an aq. soln. of a mixt. composed of sodium hydrogensulfate and (a) magnesium oxide or magnesium hydroxide and/or (b) at least one member selected from sodium dihydrogenphosphate, disodium hydrogenphosphate, sodium phosphate, magnesium sulfate, aluminum sulfate, magnesium chloride and potash alum. |
