process for the production deponierbarer products from environmentally hazardous salzgemischen

摘要

1. Process for the preparation of products which can be dumped and result from dry, for the most part water-soluble environmentally hazardous salt mixtures which evolve heat on dissolving, by adding hydraulic binders and if appropriate additives, with subsequent compaction and water-tight encasing of the shaped bodies, characterized in that the salt mixture is first pre-mixed in the dry state with 10 to 50 wt.-% cement, water and/or an aqueous plastics dispersion is then added up to a water/cement value of 0.3 - 0.6, the mixture is compacted to spherical shaped bodies while the salt mixture is still evolving heat, and these shaped bodies are then provided with a bitumen coating 0.1 - 5 mm thick and embedded in a cement matrix.
