Abstract

La invención se refiere al uso para aumentar la resistencia mecánica inicial de una composición hidráulica de al menos un copolímero obtenido por la polimerización a partir de una mezcla de monómeros que comprende: - al menos un monómero aniónico (a) que comprende un grupo insaturado polimerizable y un grupo carboxílico y - al menos un monómero (b) de la siguiente fórmula (I): H2C=(-R1)-(CH2)p-O-[(EO)n-(PO)m]H (I) en la cual: R1 representa un átomo de hidrógeno o un grupo CH3, p es igual a 1 ó 2, [(EO)n-(PO)m] representa una cadena polialcoxilada constituida por unidades etoxiladas EO y unidades propoxiladas PO, distribuidas en bloques, alternadas o aleatorias, y m y n representan números enteros que varían entre 1 y 250, siendo la suma de m y n mayor o igual a 10, siempre que la proporción molar de las unidades etoxiladas en la cadena polialcoxilada (n)/(m+n) sea estrictamente inferior al 90%.
