Abstract
Methods for plasticizing cementitious mixtures having relatively high water/cement ratio (at least 0.40 or higher) are surprisingly improved in terms of dosage efficiency, compared to conventional 'superplasticizer' polycarboxylate polymers, when the comb-type carboxylate copolymer is formed from two different polyether side chains having specifically selected monomer constituents.
