[1A11] Development of solidification techniques with minimised water content for secondary radioactive aqueous wastes in Fukushima
(7)Leaching test of CAC and CAP containing simulated secondary wastes
Keywords:Leaching test, Calcium aluminate cement, Phosphate cement, Concentrated effluent, Iron co-precipitated slurry, Carbonated slurry
Durability of CAC and CAP containing simulated secondary wastes was studied via leaching test. A significant effect of curing temperature was observed in CAP when concentrated effluent was incorporated. After leaching test, hemi- and mono-carbonate phases were formed CAC, whereas CAP did not indicate any obvious change in the product phases.
