    摘要: An early strength-enhancing admixture and cement composition is disclosed. The admixtures incorporate strength-enhancing components selected from the group consisting ofa. a nitrogenous compound of the formula ##STR1## wherein R.sub.1 =R.sub.5 A;R.sub.2 =R.sub.5 A, R.sub.5 OH, --OR.sub.6, --R.sub.6, --H, or Z;R.sub.3 =R.sub.5 A, R.sub.5 OH, --OR.sub.6, --R.sub.6, --H, or Z;A=--COOH or --SO.sub.3 H (or salts thereof)Z= ##STR2## R.sub.4 =an alkylene linking group; R.sub.5 =C.sub.1 -C.sub.10 alkylene;R.sub.6 =C.sub.1 -C.sub.10 alkyl;and at least one of R.sub.2 or R.sub.3 is R.sub.5 A, andb. a nitrogenous compound of the formula ##STR3## wherein R.sub.7 =R.sub.5 OH;R.sub.8 =R.sub.5, --R.sub.5 OH;R.sub.9 =--H, R.sub.5 OH.
