CEMENT GRINDING AUXILIARY |
| abstract |
The present invention relates to a grinding aid for a cement clinker comprising a superplasticizer based on a copolymer of styrene and maleic anhydride (SMA). The SMA is preferably a copolymer comprising side chains based on polyoxyalkylene. The use of the grinding aid makes the grinding process more efficient and improves the performance of the cement-based compositions in which the cement thus used is used. |
