DISPERSANT FOR HYDRAULIC COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a dispersant for hydraulic compositions, the dispersant having sufficient dispersion performance for hydraulic compositions and capable of improving a mixing speed upon preparing a fresh concrete. SOLUTION: The dispersant for hydraulic compositions comprises a polymer obtained by polymerizing a specified ethylene-based unsaturated monomer (A) having a polyoxyalkylene group and an ethylene-based unsaturated phosphoric acid monomer (B).
