Title (EN) USE OF ADDITIVE FOR HYDRAULIC BINDER TO PREVENT THE FORMATION OF RUST-COLORED STAINS AT THE SURFACE OF HYDRAULIC COMPOSITIONS
(FR) UTILISATION D'UN ADDITIF POUR LIANT HYDRAULIQUE POUR PRÉVENIR LA FORMATION DE TACHES DE COULEUR ROUILLE À LA SURFACE DE COMPOSITIONS HYDRAULIQUES
Abstract:
(EN) 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.
(FR) L'invention concerne un additif pour liant hydraulique comprenant : au moins une dialcanolamine comprenant de 2 à 8 atomes de carbone, et au moins un polyol choisi de préférence parmi un diol, un triol, un tétraol et des mélanges de ceux-ci, et ses utilisations en tant qu'adjuvant de broyage pour précurseur de liant hydraulique, pour prévenir la formation de taches de couleur rouille à la surface d'une composition hydraulique et/ou pour améliorer la résistance à la compression d'une composition hydraulique définie.
