| 摘要 |
The invention relates to a method for the production of a hyper-fine cement, wherein cement is wet-ground in a non-aqueous solvent, optionally in the presence of a grinding aid, thus yielding a hyper-fine cement having a particle size of D50 < 1 µm. The hyper-fine cement is suitable for sealing or reinforcing porous molded bodies, rocks, or porous formations, particularly for the gas-tight sealing of natural gas deposits, and also as fire protection of polymer materials or components made of pressed textiles or natural fibers. |
