GROUND IMPROVER COMPOSITION AND USE THEREOF
To provide a ground improver composition capable of providing excellent ground durability while suppressing corrosion of a metal structure, and to provide a use thereof.SOLUTION: The ground improver composition contains (A) a metal (meth)acrylate, (B) a polyvalent metal salt compound other than the metal (meth)acrylate, (C) an α-hydroxy acid or a salt thereof, (D) a basic compound, (E) a polymerization initiator, and (F) water. The total amount of the component (A) and the component (B) is 2.0-15 mass%. The molar ratio of the component (C) to a central metal of the component (B) is 0.1-1.0. The ground improver composition has a pH of 4.0-9.0. Preferably, the component (B) is an aluminum salt compound, and the component (C) is a C2-8 α-hydroxy acid or a salt thereof.SELECTED DRAWING: None
