<p>PROBLEM TO BE SOLVED: To provide a method for solidifying soil weak-acidly, in which soft soil is solidified to certainly obtain high-strength improved soil and the solidified soil having excellent executability and nearly neutral pH is obtained and the environmental load of which is made smaller.SOLUTION: The method for solidifying soil weak-acidly comprises: a mixing ratio decision step of deciding a mixing ratio of a solidifying material, which contains alumina cement and aluminum sulfate, to the soil to be solidified so that a mixture obtained by mixing the sampled soil being a part of the soil to be solidified with the solidifying material has the pH higher than 4.0 and equal to or lower than 6.0 and predetermined strength; and a solidification step of solidifying the obtained mixture of the soil to be solidified with the solidifying material.</p> |
