POWDERED DISPERSANT FOR HYDRAULIC COMPOSITIONS AND PRODUCTION METHOD THEREOF
The present invention is a powdered dispersant for hydraulic compositions containing a copolymer obtained by polymerizing raw material monomers containing a predetermined monomer 1 containing AO group with a number of added moles n falling within a predetermined range and a predetermined monomer 2 having a predetermined group such as a carboxylic acid group or the like, wherein a ratio of monomer 2 in the raw material monomers is 22 mass % or more, and a product of a value of n of monomer 1 and a value of mass % of the ratio is 420 or more and 2600 or less.
