Abstract:
The invention provides an admixture for a hydraulic binder composition comprising at least one cationic polymer and at least one anionic polymer, at least one of these polymers having a comb type of structure, wherein the mass ratio of the anionic polymer/cationic polymer is from 99.9/0.1 to 60/40. It also provides a process for its preparation as well as its use as a plasticizer.
