| titleOfInvention | MIXING AGENT FOR CONCRETE. |
| abstract | A concrete mixing agent comprising a copolymer-mixture, which can be obtained by copolymerizing at least one monomer (A) represented by the formula (a) and at least one monomer (B) represented by the formula (b), changing a molar ratio from (A) to (B), at least once during the course of the copolymerization: in which each of R1 and R2 represents a hydrogen atom or a methyl group, m is a number selected from zero at 2, R3 represents a hydrogen atom or ¿COO (AO) nX, p is zero or 1, AO represents an oxyalkylene having 2 to 4 carbon atoms or an oxysterene group, n is a number selected from 2 to 300 , and X represents a hydrogen atoms or an alkyl group having 1 to 18 carbon atoms; wherein each of R4, R5 and R6 represents a hydrogen atom, a methyl group or (CH2) m1COOM2, in which (CH2) m1COOM2 may be contributed with COOM1 or another (CH2) m1COOM2 to produce an anhydride, in this case M1 and M2 in these groups are not present, each of M1 and M2 represents a hydrogen atom, an alkali metal, an alkaline earth metal, an ammonium group, an alkylammonium group or a substituted alkylammonium group, and m1 is a selected number from zero to 2, in which the molar ratio of (A) / (B) in the copolymer-mixture is from 0.02 to 4 at least either before or after a change thereof, in which the maximum value of the molar ratio of (A) / (B) in the copolymer-mixture and the minimum thereof are different in each of them by at least 0.05, and in which an average ratio of (A ) to (B) by weight in the copolymer-mixture varies between 30/70 and 99/1 in the total monomers. |
