Sample 7: Sodium nitrate•crystals (Type 4.Waste). 75 g(2.6 oz) was
added to 50 g (1.8 oz) binder and processed. The material was
successfully solidified.
Sample 8A/8B: Wet basin sludge slurry (Type 2, 3, or 4 Waste). 150 g
(5.3 oz) of Sample 6 material was added to 100 g (3.5 oz) of binder and
processed. The material was transferred into specimen vials and allowed
to cure. Free water was exuded during the exothermal reaction. The
vials were retained by WHC.
Sample 9A/9B: Sodium nitrate crystals (Type 2, 3, or 4 Waste). 150 g
(5.3 oz) of crystals was added to 100 g(3.5 oz) of binder and processed.
The material was transferred into two specimen vials and allowed to cure.
The cured vials were retained by WHC.
Sample 10: Sodium sulfate decahydrate (Type 4 Waste). 50 g(1.8 oz) of
crystals were added to 50 g of binder and processed. Water was exuded
during the exotherm. The water evaporated, leaving behind salt crystals.
Sample 11: Wet basin sludgeslurry (Type 2, 3, or 4 Waste). This sample
was processed at 50:50 waste:binder ratio in an attempt to prevent
formation of free water. During the exothermal reaction, about 2.3 wt%
free water was produced.
Sample 12: Sodium sulfate decahydrate (Type 4 Waste). 75 g(2.6 oz) of
crystais were added to 50 g(1.8 oz) of binder. For this test, the
polymer extender was not added to the binder. This caused less heat to
be produced during the exothermal reaction and a significant reduction in
the amount of free water produced. The free liquid evaporated, leaving
dry crystalline powder on the surface of the sample. The observers
estimated that less than 0.5 wt% free liquid had been produced.
Sample 13: Wet basin sludge slurry (Type 2, 3, or 4 Waste). This sample
was processed at 75 g (2.6 oz) waste to 50 g (1.8 oz) binder. No
extender was added to the binder. The material produced 2.1 wt% free
liquid.
Sample 14: Wet ammonium sulfate (Type 1 Waste). Water was added to the
ammonium sulfate crystals to produce 10 wt% moisture to simulate LETF
filter cake. The material was successfully solidified at 60 wt% loading
(75 g[2.6 oz] wet salt:50 g [1.8 oz] binder) with no extender added to
the binder.
Sample 15A/158: Sodium sulfate decahydrate (Type 4 Waste). 150 g
(5.3 oz) of the crystals was added to 100 g (3.5 oz) of binder without
extender. The material was transferred into two specimen vials retained
by WHC. Traces of water were exuded, leaving small spots of dry crystals
on the surface of the specimens.
