-from tank 8D-2 based upon a-nominal 130 inch supernatant heel.
It will' confirm the accuracy of data and' observations generated by laboratory simulantr 'and determine if any unforeseen constituent are having an undesirable-effect on the cement. product.
.6.0 ? Procedure' 6.1 Prerequisite
-Oven or environmental chamber-should be set at proper temperature.as-defined in sec 6.1.20 and monitored by a calibrated thermocouple or thermometer per PRD 8.0 Rev 1 Balances shall be calibrated according to ACP 7.1 Safety procedures should be reviewed in ACP 7.2 DLSO460: 3RM.-.

WNS TP-034 Rev. 0 6.1.1 A sufficient amount of liquid from WVNS TP 032, Sludge Wash #1 shall be used to generate at least 100 milliliters of 33 percent solid sludge wash liquid. This liquid shall be placed in a 250 ml beaker and evaporated slowly, while stirring to reduce splattering.
The liquid before concentration shall be analyzed for total dissolved solids, density, pH, gross alpha and gross beta.
The liquid shall ba reduced to approximately three-quarters of its initial volume. At this point the total solids will be determined by ACM 2401.
If the total solid content is between 29 and 33 percent, the evaporation will stop and the solution allowed to cool.
If the solid content is lower than 29 percent, evaporation will continue and the liquid tested periodically by ACM-2401 until the specified range of the solids is achieved.
At this point the total solid content will be confirmed by ACM 2501, 6.1.2 If the liquid is reduced to the point were solids are falling out of solution due to over evaporation, the evaporation should stop and nanopure water should be added in small increments and the solutien should be allowed to stir. Water and stirring shall be used to redissolve the solids.
A total solid determination should be made and an appropriate amount of water added to achieve the total solids specified.
If any type of unusual occurrences are observed during evaporation, the cognizant scientist should be notified immediately.-
If solids form during evaporation and the percent solids are within the specified range, the concentration shall be filtered and the solids analyzed for the test parameters.

6.1.4 Make a 5 percent antifoam solution. Weigh 5.00 +/- 0.05 gs of well mixed AF9020 in a 100 ml volumetric flask and dilute to the manufacturer's mark with nanopure water. Mix well and transfer to a beaker with a magnetic stir bar and stir continuously on a stir plate.
6.1.5 Prepare 200 gs 5.7 percent calcium nitrate tetra-hydrate / cement mixture by adding 11.4 gs calcium nitrate tetra-hydrate to 188.6 gs Portland Type I cement in a 500 ml beaker and mix the dry ingredients thoroughly.
6.1.6 Use a 500 ml plastic bottle to make a mixing vessel by evenly cutting off the tip and producing an open ended cylinder.
