Zusammenfassung:A method for preventing formation of rust-colored stains on the surface of a hydraulic composition includes mixing the hydraulic composition with an additive for hydraulic binder including at least a dialkanolamine including from 2 to 8 carbon atoms, and at least a polyol preferably chosen from a diol, a triol, a tetraol and mixtures thereof. Other uses include a grinding aid for hydraulic binder precursor, and/or improving the compressive strength of a set hydraulic composition.
