Abstract
The present invention pertains to the use, in the manufacture of an aqueous formulation with a hydraulic binder base, of a combination of at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophilic group, and at least one ASE acrylic polymer. This results in improving the workability of said formulation, without causing a segregation phenomenon.
