Abstract
The invention pertains to improving the workability of an aqueous formulation with a hydraulic binder base using a combination between 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 comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophobic group.
