FLUIDIZER FOR A HYDRAULIC BINDER COMPRISING A SULFOALUMINOUS CLINKER

摘要

The present invention relates to the use of a polymer as a fluidizer for a hydraulic binder comprising a sulfoaluminous clinker, the polymer comprising in molar percentages: at least 25 % of a first unit with a base of phosphorus; and more than 40 to 65 % of a second polyoxyalkylene unit; the polymer comprising at least 30 % of units comprising a negative charge; and more than 50 % of the units comprising a negative charge being a first unit with a base of phosphorus.
