Process for preparing hydraulic binding materials of high bonding capacity from glassy pyrogenic rocks |
摘要 |
There is disclosed a process for preparing hydraulic binding materials having a high bonding capacity, starting from glassy pyrogenic rocks. According to the invention glassy pyrogenic rocks are mechanically activated by grinding. The activation time is 0.5 to 36 hours, preferably 4 to 12 hours, and the mechanical stress applied is higher than in case of the conventional fine grinding. The activated product is thereafter admixed with one or both of lime and cement.
