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 polycarboxylate polymer is formed from particularly small-sized, specifically selected monomer constituents: (A) polyoxyalkylene monomer represented by the structural formula (R)(R)C═C(R)((CH)(CO)O(CH)(AO)R) wherein (AO)represents linear ethylene oxide groups and p is 5-23 and more preferably 5-15; (B) unsaturated carboxylic acid represented by (R)(R)C═C(R)(C(O)OM) wherein M represents an alkali metal, the ratio of component A to component B being 20:80 to 50:50; and, optionally, (C) a hydrophilic monomer represented by (R)(R)C═C(R)(CX) wherein R, R, and Reach represent hydrogen or methyl group, and X represents C(O)NH, C(O)NHR, C(O)NRR, SOH, CHSOH, or C(O)NHC(CH)CHSOH, or mixture thereof, wherein R, R, and Reach represent a Cto Calkyl group.
