Abstract
The present invention relates to admixtures, especially a dispersant for solid particles, in particular a dispersant for mineral binder compositions, comprising: a) a superplasticizer and b) a copolymer having a polymer backbone and side chains bonded thereto, comprising at least one ionizable monomer unit M1 and at least one side chain-bearing monomer unit M2, wherein the copolymer has a nonrandom distribution of the monomer units M1 and/or the monomer units M2 in a direction along the polymer backbone, and wherein the superplasticizer and the copolymer differ from a chemical and/or structural point of view.
