Solidification of concentrates of radioactively contaminated natural waters by cementation
- 28 Downloads
This article concerns the solidification of concentrates (up to 195 g/l) of radioactively contaminated natural waters, whose salt content is determined mainly by bicarbonates, chlorides, and sulfates of alkali and alkaline-earth metals. The use of various types of Portland, slag, and alumina cements for this purpose is considered. It is shown that strong, water-resistant cement compounds suitable for burial in soil repositories can be obtained using appropriate binders. 5 tables, 7 references.
