Document Type and Number:
Japanese Patent JP2017178645
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersant for precast concrete composition which imparts sufficient flowability to concrete, promotes a coagulation rate, and can impart excellent strength by curing in a short time.SOLUTION: A dispersant for precast concrete composition contains a polycarboxylic acid-based copolymer obtained by copolymerization of a monomer (I) made from acrylic acid and/or acrylate, a monomer (II) made from methacrylic acid and/or methacrylate, a monomer (III) made from a monomer (A) represented by general formula (1) and/or a monomer (B) represented by general formula (2), and other monomer (IV) copolymerizable with the monomers (I) to (III), in a ratio of (I):(II):(III):(IV)=10 to 80 wt.%:1 to 50 wt.%:1 to 90 wt.%:0 to 50 wt.% (where (I)+(II)+(III)+(IV)=100 wt.%), or a salt thereof.SELECTED DRAWING: None
