Liquid mixture is used for foundation stabilization, and material uses the construction method for foundation stabilization and basement process

摘要

PROBLEM TO BE SOLVED: To provide a liquid admixture for ground stabilization that not only improves the workability by fluidization of slime but also reduces the elution amount of hexavalent chromium, to provide a material for ground stabilization and to provide a construction method for ground stabilization.SOLUTION: The liquid admixture for ground stabilization contains a lime sulfur mixture which is a solution having a pH of 10 or more, an oxidation reduction potential (ORP) of -450 mv or less and an MgO content of 0.3% or more; is used in an amount of 0.01 to 10 pts.mass based on 100 pts.mass of cement; and is produced by further mixing with one or two kinds of liquid water-reducing agents selected from among naphthalenes, melamines, aminosulfonic acids, polycarboxylic acids and polyethers. The material for ground stabilization is produced by mixing the liquid admixture for ground stabilization, water and cement. The construction method for ground stabilization comprises injecting the material for ground stabilization into the ground and mixing with soil to lower the viscosity.SELECTED DRAWING: None
