Powdery dispersant composition for hydraulic composition |
| abstract |
The present invention pertains to a powdery dispersant composition for a hydraulic composition, said powdery dispersant composition comprising the following particles (A) and (B), wherein the surface tension at 25°C of an aqueous solution or aqueous suspension having a concentration of 5 mass% of the powdery dispersant composition for a hydraulic composition is 20.0-50.0 mN/m inclusive. <Particles (A)> Particles comprising the following components (A1) and (A2), having a median diameter (D50; μm) of 90-600 μm inclusive, and containing particles having a particle diameter of 70 μm or less at a ratio of 15 vol% or less. [Component (A1)] A copolymer comprising specific structural units (1) and (2) in which the melting points of all monomers constituting the copolymer are from -80°C to 80°C inclusive. [Component (A2)] A nonionic surfactant wherein the surface tension at 25°C of an aqueous solution or aqueous suspension having a concentration of 5 mass% thereof is 20.0-50.0 mN/m inclusive. <Particles(B)> Particles made of an inorganic compound and having a median diameter (D50; μm) of 1-50 μm inclusive. |
