An early strength-enhancing admixture and cement composition is disclosed. The admixtures incorporate strength-enhancing components selected from the group consisting of: a) a nitrogenous compound of formula (I) wherein R1= R5A; R2= R5A, R5OH, -OR6, -R6, -H, or Z; R3= R5A, R5OH, -OR6, -R6, -H, or Z; A= -COOH or -SO3H (or salts thereof); Z= (1); R4= an alkylene linking group; R5= C1-C10 alkylene; R6= C1-C10 alkyl; and at least one of R2 or R3 is R5A; and b) a nitrogenous compound of formula (II) wherein R7= R5OH; R8= R5, -R5OH; R9= -H, R5OH.

L'invention concerne un adjuvant précoce augmentant la résistance et une composition de ciment. Les adjuvants comprennent des composants augmentant la résistance, choisis dans le groupe comprenant: a) un composé azoté de formule (I), dans laquelle R¿1?= R¿5?A; R¿2?= R¿5?A, R¿5?OH, -OR¿6?, -R¿6?, -H, ou Z; R¿3?= R¿5?A, R¿5?OH, -OR¿6?, -R¿6?, -H, ou Z; A= -COOH ou -SO¿3?H (ou des sels de celui-ci); Z= formule (1); R¿4?= un groupe de liaison alkylène; R¿5?= alkylène C¿1?-C¿10?; R¿6?= alkyle C¿1?-C¿10?; et au moins R¿2? ou R¿3? est R¿5?A, et b) un composé azoté de formule (II), dans laquelle R¿7?= R¿5?OH; R¿8?= R¿5?, -R¿5?OH; R¿9?= -H, R¿5?OH.
