Abstract
The present invention relates to a dispersant for a hydraulic composition, containing a polymer obtained by copolymerizing a specific monomer 1 such as an ethylenically unsaturated carboxylic acid derivative having a polyoxyalkylene group, a monoester phosphate-based monomer 2, a diester phosphate-based monomer 3, and an unsaturated carboxylic acid-based monomer 4, at pH 7 or less.
