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 17):
A method for achieving low-to-mid-range reduction of hydration water in concrete or mortar mixes using at least one polycarboxylate comb copolymer, comprising:\n combining with water and cement to form a hydratable cementitious mixture, wherein low-range and mid-range water reduction is achieved at below 12 percent water cut and wherein the water/cement ratio is at least 0.45 and no greater than 0.75, at least one air detraining agent and the at least one polycarboxylate comb copolymer having a weight average molecular weight of 14,000-25,000, the at least one polycarboxylate comb copolymer being formed from the following monomer components: (A) polyoxyalkylene monomer represented by structural formula: wherein R 1  and R 2  individually represent hydrogen atom or methyl group; R 3  represents hydrogen or \u2014COOM group wherein M is a hydrogen atom or an alkali metal; (AO) p  represents linear repeating ethylene oxide groups and \u201cp\u201d represents the average number of repeating ethylene oxide groups and is an integer from 5 to 23; \u201cm\u201d represents an integer of 0 to 2; \u201cn\u201d represents an integer of 0 or 1; \u201co\u201d represents an integer of 0 to 4; and R 4  represents a hydrogen atom or C 1  to C 4  alkyl group;\n (B) unsaturated carboxylic acid monomer represented by structural formula: \n wherein R 5  and R 6  individually represent hydrogen atom or methyl group; R 7  represents hydrogen or \u2014COOM group; M is a hydrogen atom or an alkali metal; and\n (C) unsaturated, water-soluble hydrophilic monomer represented by structural formula: \n wherein R 8 , R 9  and R 10  each independently represent a hydrogen atom or methyl group; 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, C(O)NHC(CH 3 ) 2 CH 2 SO 3 H, or mixture thereof, wherein R 11 , R 12 , and R 13  each independently represent a C 1  to C 5  alkyl group; and\n wherein the molar ratio of component (A) to component (B) is from 20:80 to 50:50, and further wherein the molar ratio of component (C) to the sum of component (A) and component (B) is 0.25:99.75 to 10:90.
