USE IN HYDRAULIC BINDER COMPOSITION OF DRY-GROUND CALCIUM CARBONATE WITH (METH)ACRYLIC ACID COPOLYMER AND ALKOXY OR HYDROXY POLYALKYLENE GLYCOL FUNCTION

摘要

The invention resides in the use in a composition with a hydraulic binder base, of a calcium carbonate characterised in that it is obtained by dry-grinding, firstly, and in that it is dry-ground in the presence of a grinding aid agent which is a copolymer of (meth)acrylic acid with a monomer containing an alcoxy or hydroxy polyalkyleneglycol group, secondly. The invention also concerns the compositions with a hydraulic binder base thus obtained.
