| Popis: | Possible routes of conversion of belite sludge into mineral paragenesis, which is stable under hypergene conditions, changes the physical structure of sludge, and reduces its filtrating properties, are investigated using thermodynamic modeling methods. It is found that the filtration drainage may be reduced by clinker minerals (carboaluminates and tobermorite) formed by using finely dispersed colmatant prepared from amorphous silicon dioxide. Finely dispersed powder from silicon production (cyclone collector of gas-cleaning systems) may be used as a raw material in colmatant production. |
