Abstract
A filler for a concrete structure is provided. The filler includes an organic-inorganic composite hydrogel (A). The organic-inorganic composite hydrogel (A) has a three-dimensional network structure that includes a polymer of a water-soluble organic monomer and includes a water-swellable clay mineral. The filler has a water pressure resistance of 0.2 MPa or greater. The filler for a concrete structure has excellent workability and various excellent physical properties in terms of, for example, adhesion to wet surfaces and resistance to water pressure. Accordingly, the filler is suitable for use as a filler for joints and cracks of concrete structural objects.
