Abstract
A comb polymer that is a dispersant in a binder composition includes an alkaline activating agent, wherein the activating agent is intended for activation of a latently hydraulic and/or puzzolanic binder, and wherein the comb polymer has a polymer backbone formed from a plurality of backbone monomers and a plurality of polymeric side chains each formed from a plurality of side chain monomers and bonded thereto, and wherein at least some of the backbone monomers have one or more ionizable groups, and features a structure constant K of the comb polymer, defined as K=[(N−1)z]/nPN×10, at least equal to 70, where n is the average number of side chains per comb polymer molecule, N is the average number of backbone monomers per side chain, P is the average number of side chain monomers per side chain, and z is the average number of ionizable groups per side chain-free backbone monomer.
