| abstract |
The present invention relates to the use, in the manufacture of an aqueous formulation based on hydraulic binders, of a combination between at least one comb copolymer having a (meth) acrylic backbone, on which are grafted side chains terminated by a hydrophilic group, and at least one comb copolymer having a (meth) acrylic backbone, on which are grafted side chains terminated by a hydrophobic group. It is possible to improve the workability of said formulation, without causing segregation phenomenon. |
