USE IN HYDRAULIC BINDER COMPOSITION OF DRY-GROUND CALCIUM CARBONATE WITH (METH)ACRYLIC ACID COPOLYMER AND ALKOXY OR HYDROXY POLYALKYLENE GLYCOL FUNCTION |
| 摘要 |
<p>The invention relates to the use, in a hydraulic binder-based composition, of a calcium carbonate characterized in that it is obtained by dry-grinding, and in that it is dry-ground in the presence of a grinding aid agent that is a (meth)acrylic acid copolymer with a monomer carrying an alkoxy or hydroxy polyalkylene glycol function. The invention also concerns the hydraulic binder-based compositions thus obtained.</p> |
