Abstract
(EN)
The present invention provides an additive for hydraulic compositions, which is capable of decreasing the viscosity of a hydraulic composition, while attenuating the influence of fine particle components or clayey materials contained in an aggregate. An additive for hydraulic compositions, which contains, as a component A, a polymer that has a constituent unit formed from an acrylic acid and/or a salt thereof, while having a mass average molecular weight of 1,000 or more but less than 100,000, and as a component B, a vinyl copolymer that has a constituent unit 1 and a constituent unit 2 in each molecule, with the content of the constituent unit 1 being 1-99% by mass and the content of the constituent unit 2 being 1-99% by mass; and a hydraulic composition.
