WNS TP 028B WATER TO CEMENT RATIO VARIANCE IN SIMULATED SLUDGE WASH REV. 0 1.0 SCOPE 1.1 This test procedure is bein5 written to complete the request initiated under WNS TRQ 028 and WNS TPL-70 011.

The objective of this overall testing criteria is to better define the effects of water to cement ratio on the simulated sludge wash cement's get time, bleed water, penetration resistance

..d compressive streng.th.

According to results obtained from WNS-TP 028A and the Plackett-Burman screening matrix used in this test procedure the only observed effect on the cement waste form was determined to be water to cement ratio variauce.

1.2 The work will include 18 2-inch square cubes with water to cement ratios from 0.45 to 0.80 at 0.05 increments however at 0.65, 4 cubes will be made at this increment.

After an appropriate curing period, per section 5,0, the s

2-inch square cubes will be subjected to compressive strength testing per section 6.2.1.

i' 1.3 The compressive strength, bleedwater, pH of the bleed water, and penetration resistance will be measured and recorded for each cube as part of ACM-4801.

ACM 2601 "pH" (Electrode) 5.0 CENERAL UFORMATION Test Procedure VVNS TP 028A Revision 1 was used to evaluate the effects of 13 variables in the cement vaste form production through the use of the Plackett Burman Screoning test.

The one-variable that showed any significant effect on the compressive strength of the cement and secondary effects of excessive bleedwater and gel time was water to cement ratio.

This effect was clearly shown to have an almost linear correlation between water / cement and compressive strength and was also demonstrated in VVNS TP 025 in the total solids-variance and vetet to cement

ratio, This effect vill be more clearly defined in this test procedure by the use of a single variance analysis of water to cement ratio over a smaller defined window with the evaluation of a large set of data points.

The water to cement ratio will be evaluated from 0.45 to 0.8 at increments of 0.05 and a total of RLA0510:3RM 5

VVNS TP 029A TEST COMMENCEMENT DATE 4/18/91 TEST COMPLETION DATE 4/25/91 Engineering Release #2149 1.0 OBSERVATIONS / COMMENTS /

REFERENCES:

After release of WVNS TRQ 029, it was realized that the tests could not be completed as requested. Test Plan WVNS TP 029A, in fact was written and authorized as a substitute for a pertion of the work specified in VVNS TRQ 029.

Specifically, objectives 2.11, 2.12, and 2.14 of the test request were completed per test procedure VVNS TP 029A.

Test procedure VVNS TP 029A combined the remaining portions of laboratory decontaminated sludge wash solutions from previous experiments into one collective sample.

The sample was sampled for analyses and then concentrated prior to creation of a cement cube.

The combined wash solution was yellow and slightly cloudy with no observable solids collecting at the bottorn of the lab vessel.

The original laboratory solutions were filtered'before being concentrated.

Following completion of the tests, a test exception was written against the original test request (TE WVNS TRQ 029-1) cancelling all other portions of the objectives.

The work, as originally defined, is scheduled to be completed under different test requests:

WVNS TPQ 032, WVNS TRQ-033, and WVNS-TRQ 034

3.0 CONCLUSION

S / ACCEPTABILITY OF RESULTS/0BJECTIVES MET:

The acceptability of the three objectives retained from WNVS-TRQ-029 are presented below.

3.1 Analyze Concentrates (objectivy 2.11)

Activity Analyze the concentrates used in the preparation of a cement cube per the analyses listed in Table 1.

/

WPC1047:3PR -

VVHS.TSR4*;

Rev. 0 Task Accomplished This task remains open, pending the re start of the Analytical 6 Process Chemistry ICP AES instrument for radioactive samples.

Physical data for the concentrates are a density of 1.23 ga/a1 with a weight percent total dissolved solids (TDS) of 29.7.

This meets the defined acceptance window of 3112 welght percent TDS (section 1.2 of VVNS TP 029A).

3.2 Prepara a Reference 2 inch Cement Cube (objective 2.12)

Activity Use the concentrates to prepare a reference 2 inch cement c:ube per the standard Analytical Chemistry Method (ACM).

Task Accomplished The cube was prepared. A cement slurry density of 1.76 gn/mi was measured. A gel time of 35.5 minutes in the A&PC lab matches very well to general guides maintained by L. E. Michnik, A6PC Cognizant Scientist.

The results prior to curing are very acceptable for a cement vaste form that meets the 10 CFR 61 criteria and general guides for CSS operation per VVNS PCP 01.

3.3 Perform Tests on the Cement Cube (objective 2.14)

Activity Check for bleedwater at the end of a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period following pouring of the cement cube.

Perform a penetration test on the cube after a 61 hour7.060185e-4 days <br />0.0169 hours <br />1.008598e-4 weeks <br />2.32105e-5 months <br /> cure at elevated temperature; also complete a destructive compressive strength measuretnent of the cube following a 7 day curing period.

Task Accomplished No bleedwater was detected for this cement recipe at the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> mark.

An initial curing cycle of 61 hours7.060185e-4 days <br />0.0169 hours <br />1.008598e-4 weeks <br />2.32105e-5 months <br /> at 8812'c was completed.

Penetration testing following the 61 hour7.060185e-4 days <br />0.0169 hours <br />1.008598e-4 weeks <br />2.32105e-5 months <br /> period yielded a value of >700 psi (beyond range of penetrometer) which is typical and very acceptable for labotatory cubes.

Following completion of a seven day curing period (total time),

destructive compression testin6 on the cube was performed.

The cube was compressed using templates (not recognized yet in ASTM C 109).

The result (694 psi) exceeds the minimum mean strength (500 psi) specified in the NRC Technical Porition on Waste Form. Revision 1.

For comparison three cubes were prepared in the A&PC lab using reagent _ grade chemicals to simulate the concentrates used in this experiment.

The-three cubes used a simulant recipe as show.i in Table 2.

Trace levels of organics in the recipe-are about 30 percent higher than the level defined for sludge wash solution y

I with a 129 inch heel.

W14S.TSR 029 Rev. O The results of compressive strength crushing (using templates) for the three cubes were 841, 1079, and 1138 psi.

Combined with a t statistic of 2.92, the range of strengths that should cover 95 percent of a gausian distribution go from 560 psi up to 1478 psi.

This implies that the simulant cubes are exhibiting the same compressive strengths as the laboratory concentrates cube.

The conclusion of this work is that the nominal. recipe developed for sludge washing is acceptable although the cube was representative of sludge washing with a 32. inch heel.

Additional experiments are defined in WNS TRQ 032, WNS TRQ 033, and WNS Tp.Q 034 to confirm the cement recipe for sludge washing with a 129 inch heel.
