Zusammenfassung:The invention concerns an additive for hydraulic binder comprising: - at least a dialkanolamine comprising from 2 to 8 carbon atoms, and - at least a polyol preferably chosen from a diol, a triol, a tetraol and mixtures thereof, and the uses thereof as a grinding aid for hydraulic binder precursor, to prevent the formation of rust-colored stains at the surface of a hydraulic composition and/or to improve the compressive strength of a set hydraulic composition.
