Abstract (en)
[origin: WO2016146935A1] The invention concerns the use, for increasing the early-age mechanical resistance of a hydraulic composition, of at least one copolymer obtained by polymerisation from a mixture of monomers comprising: - at least one anionic monomer (a) comprising a polymerisable unsaturated function and a carboxylic group; and - at least one monomer (b) of following formula (I): H2C=C(-R1)-(CH2)p-O-[EO)n-(PO)m]-H (I) in which: R1 represents a hydrogen atom or a CH3 group, p is equal to 1 or 2, [(EO)n-(PO)m] represents a polyalkoxylated chain consisting of ethoxylated units EO and propoxylated units PO, distributed into blocks, alternating or statistical, and m and n represent integers varying between 1 and 250, the sum of m and n being greater than or equal to 10, provided that the molar proportion of the ethoxylated units in the polyalkoxylated chain (n)/(m+n) is strictly less than 90 %.
