Cement admixture and cement composition |
| abstract |
The present invention provides a cement admixture and a cementncomposition, both of which displays little dependence of the water-reducibilitynupon temperature in that these cement admixture andncement composition involve little slump loss at high temperature andnlittle increase in the amount of addition at low temperature. The cementnadmixture comprises either or both of the following components:ncopolymer (A) which includes constitutional unit (I) of general formulan(1) below and constitutional unit (II) of general formula (2) below asnessential constitutional units and may further include constitutional unitn(III) of general formula (3) below, wherein the content of constitutionalnunit (III) is 45 weight % or less of copolymer (A); and copolymer salt (B)nwhich is obtained by further neutralizing copolymer (A) with an alkalinensubstance. |
