COPOLYMERS HAVING A GRADIENT STRUCTURE AS DISPERSANTS FOR ALKALINE-ACTIVATED BINDING AGENTS

Abstract

The present invention relates to the use of a copolymer as a dispersant in a binder composition comprising an alkaline activating agent, wherein the activating agent is particularly suitable for the activation of latent hydraulic and / or pozzolanic binders, wherein the copolymer has a polymer backbone and side chains bound thereto and at least one ionized monomer unit M1 and at least one monomer unit M2 having a side chain, and wherein the copolymer has a gradient structure of at least one A portion in the direction along the polymer backbone with respect to the ionized monomer unit M1 and / or with respect to the monomer unit M2 having a side chain.
