    Abstract: PROBLEM TO BE SOLVED: To provide a dispersion maintaining agent for hydraulic composition that excels in both fluidity retention and viscosity retention, and to provide a dispersion maintaining agent that exhibits excellent fluidity retention and viscosity retention without depending on the type of hydraulic powder.SOLUTION: The dispersion maintaining agent for hydraulic composition comprises a copolymer obtained by polymerizing a specific monomer 1 represented by general formula (1) and a specific monomer 2 represented by general formula (2) in which a corresponding alcohol compound satisfies a specific property. In the constituent monomers of the copolymer, the ratio of the monomers 1 is within a specific range, and a specific monomer is used as at least some of the monomers 2, and the ratio of a monomer having an acid group or a group resulting from neutralization thereof is 5 wt.% or below.
