DISPERSANT COMPOSITION FOR HYDRAULIC COMPOSITIONS
PROBLEM TO BE SOLVED: To provide a dispersant composition for hydraulic compositions that can maintain the fluidity of cement milk and suppress the viscosity increase of soil cement.SOLUTION: A dispersant composition for hydraulic compositions contains a polymer having a monomer unit having a carboxylic acid group (A) and a sugar compound with a molecular weight of 1,000 or less (B) and has a pH at 22°C of 7.5 or less. Preferably, the polymer (A) has a degree of neutralization of 0% or more and 75% or less. More preferably, the composition contains an acid (C) with its content being 0.03 wt.% or more in the composition.SELECTED DRAWING: None
