Verfahren zur Konditionierung von wasserloeslichen Sonderabfaellen

摘要

1. Process for conditioning water-soluble special-category wastes, in particular of salts and salt mixtures, by mixing with cement, water, aggregate and optionally additives, and producing from these mixtures waste structures which have a peripherat layer which is free from special-category waste, characterized in that, with the aid of moveable equipment, the waste structure is built up in layers in one operation by initially introducing, as the base layer, a cement/water mixture which is free from special-category waste and has a water/cement ratio of from 0.2 to 0.8, then, in order to build up the waste structure, this cement/water mixture is admixed with the spexial-category waste to be dumped in a concentration increasing from 0 to 70% by weight from the outside inward and from bottom to top, the water/cement ratio being increased to 1.2, and the content of special-category waste is subsequently gradually reduced back to 0% by weight and the water-cement ratio is reduced back to the previously established value between 0.2 to 0.8 in the direction of the top layer and the lateral peripheral zones.
