GROUND IMPROVER COMPOSITION AND USE THEREOF
To provide a ground improver composition which imparts good strength and durability to a gelled product and is excellent in corrosion inhibiting properties for an improved ground, and to provide a use thereof.SOLUTION: The ground improver composition contains (A) a metal (meth)acrylate, (B) a polyvalent metal salt compound having a basicity of 60% or more, (C) a polymerization initiator, and (D) water. The total amount of the component (A) and the component (B) is 2.0-15 mass%. Preferably, the component (C) is a peroxide having 15 or less carbon atoms, and the polyvalent metal salt compound as the component (B) is aluminum chloride.SELECTED DRAWING: None
