PROCESS FOR PROCESSING MOIST COMPOSITIONS CONTAINING POLLUTION-CAUSING SUBSTANCES AND COMPOSITION |
| 摘要 |
<p>A waste sludge as obtained from gases evolved during steel preparation in converters by blowing oxygen through said liquid steel is mixed with fly ash thereby forming particulate material. Preferably the final products contain 25 - 35% of fly ash and at most 5% of a curing activator. The hardness of the particles may be improved by moistening the surface of the particles with water.</p> |
