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 1 )(R 3 )C═C(R 2 )((CH 2 ) m (CO) n O(CH 2 ) o (AO) p R 4 ) wherein (AO) p  represents linear ethylene oxide groups and p is 5-23 and more preferably 5-15; (B) unsaturated carboxylic acid represented by (R 5 )(R 7 )C═C(R 6 )(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 8 )(R 9 )C═C(R 10 )(CX) wherein R 8 , R 9 , and R 10  each represent hydrogen or methyl group, and X represents C(O)NH 2 , C(O)NHR 11 , C(O)NR 12 R 13 , SO 3 H, C 6 H 4 SO 3 H, or C(O)NHC(CH 3 ) 2 CH 2 SO 3 H, or mixture thereof, wherein R 11 , R 12 , and R 13  each represent a C 1  to C 5  alkyl group.

Claim (Index 30):
The method of  claim 17  further comprises combining with the water, cement, and the at least one polycarboxylate comb copolymer, at least one other agent chosen from gluconate, lignosulfonate, naphthalene sulfonate, alkanolamine, and defoamer.
