| 摘要 |
The invention relates to an additive, in particular a dispersant for solid particles, in particular a dispersant for mineral binder compositions, comprising the following: a) a superplasticizer and b) a copolymer with a polymer backbone and side chains bonded thereto, comprising at least one ionizable monomer unit M1 and at least one side chain-supporting monomer unit M2. The copolymer has a non-random distribution of the monomer units M1 and/or the monomer units M2 in a direction along the polymer backbone, and the superplasticizer and the copolymer differ chemically and/or structurally. |
