==
Description:==
Construction projects require a quality assurance (QA) programthat, among other things, involves the selection of test methods, establishing test criteria, testing the fresh concrete, testing the hardened concrete, statistical analysis of test results, and follow-up procedures...
Fresh concrete is tested for its workability (Slump test)i temperature, and air content.
Hardened conc~rete is tested for its strengthunder compressive loading. The purposes of strength tests of concrete are to determine compliance with a strength specification and to measure the variability of concrete (ACI 214provides a discussion of methods and analysis for strength tests of concrete).
It is necessary to establish the quality of the test program in order tobe able to evaluate its results and conclusions.
Data. to be collected and Analyzed:
1.Review project QA program 2.Review test procedures and results 3.Review analysis and reporting procedures 4.Analyze follow-up procedures (NCRs,....)
5.Anaiyze test program for compliance with industry standards.
Verified Refuting Evidence (see following. discussion): Verified Supporting.
a.The established QA program was comprehensive and covered all critical testing areas. Evidence:
b.Pour records show compliance with the parameters ofthe QA program. None c.Although some strength test results appear to be erroneous, the overall program meets industry standards for Good Control.
When errors are found in individual strength tests itis possible to make proper evaluation of the concrete strength by analyzing earlier or later tests from the same cylinder. set. Itis therefore believed that no under-strength concrete was.
placed as a result of inadequate testing. * "
Conclusions.:
Testing program was adequate and did not contribute to thedelamination.
Iissue May identify additional perspectivelon this.

3.7 Inadequate Testing Discussion:
A)Fresh concrete issubjected to a set of "acceptance" tests that determine whether it should be used or discarded. 'The test cri.te.ria and procedures Were..
established inPTL'S documents shown inFMV 3.7 Exhibit 3and specifications FM 3.7 Exhibit 2.
I. The Slump test isa practical test for workability that isalso useful indetermining if the concrete was modified or. if it'was mixed for. extended period of time. Project specifications called for Slump of 4.5" at the pump~and.4" at the discharge (FMV 3.7 Exhibit.7). Analysis of. pour records, indicate that astrict inspection/testing process was followed and that multiple trucks were rejected when the allowed slump. wa s exce eded.
(Selected examples of reported tests and rejection handling in FMV 3.7 Exhibit 4). Amore complete discussion can be found inFMV 2.3.
ii. Air content was measured using the pressure meter -on selective trucks. The specifications called for air in the range of .3-6%. All tests fell in that. range and no concrete was rejected because of air. (Selected examples of reported tests, in FM 3.7 Exhibit 4)
Iii. Ambient and concrete temperatures were recorded on selected. loads. Trucks were rejected (or accepted after Engineer's approval) when concrete temperature exceeded 70 degrees.. (specifications at FMV 3.7 Exhibit 2; examples of reported tests in FMV 3.7 Exhibit 4'and rejection handling inFMV 3.7-Exhibit 5). Amore complete discussion can be found in FMV 2.5.
b)Hardened concrete was tested for compliance with design strength over time by crushing site-made cylinders after 7, 28, and 90 days.,
- i. Records of Statistical analysis of compressive tests as recommended by Ali 214 were not found from original construction time.
ii. Spot checks of random test results revealed problems with laboratory streng th tests. An example in FM 3.7 Exhibit 6 reporAts test results from two adjacent samples taken on 2/16/73 from pour 712RB. Cylinder 2181 shows normal strength gain between 7 and 28 days (28%) and very.
small gain between 28 and 90 days (7%).. Cylinder 2182 shows small strength gain between 7 and 28 days (7o) and very large gain between 28 and 90 days (37%).. At 28 days cylinder 2181 was 28%stronger than cylinder 2182i whereas at 90 days the trend rever.sed and 2181 was 10% weaker than 2182. The most likely explanation istesting error at 28 days.
According to the pour tickets these two loads were practically identical and in full compliance with the mix design (FM 3.7,Exhibit 7).1 There iisno record of concern or corrective measures arising from these tests. w r ( 'Par ofgthereporsl uded iii. A design analysis was performed on concrete placed, in Class I structures in the year 2000 (for unrelated.purpose). retin
- FM 3.7 Exhibit 8. Its significant conclusions, after analyzing strength test data from all concrete cylinders, was that the distribution followed hnin the expected bell shape and the various mixes used on the project were statistically similar in strength properties.:. .

A 3.7 Inadequate Testing, (cont.)
Discussion (cont.):
iv. Current analysis of all cylinders from 5000 psi concrete placed in the Reactor Building (RB).is included in FM 3.7 Exhibit 9. Besides providing a.
complete picture of the 28 days strength tests, it established that the test program met ACl 214's requirements for "Good" Standard of Concrete Control (ACI 214, Table 3.2 assigns Good control when Standard Deviation (StD) is in the range of 500-600 psi; Excellent control requires StD smaller than 400 psi). 200 tests for* mix 727550-2 had a StD of 541 and 239 tests for mix DM-5 had-a StD of 508.
The lower "Standard of Control" may be explained by the multiple mix-designs used, and by testing problems as demonstrated above. Although lower, it is considered acceptable for general construction testing.

- 2. Special finish for the above surfaces shall be performed as follows:
.. As soon as, tMe VOK specified in Itea 2-:04.5 a&*-ben per- I formed and the pointing mortar sufficiently set, the surfaces
.s.. .be vatted4 with -a-brush and rubbed.vith-a- Ns.. 16 -eazbo-rundum stone or an abrasive of equal quality, bringing the surface to a paste. The rubbing shall be continued enough to remove all form marks and projections producing a smooth" dense surface without pits or irregularities. The material which, in the above process has been ground to a paste, shall be carefully spread, or brushed uniformly over the entire area and allowed to "reset." No additional mortar shall be added during this operation.
- b. The final finish shall be obtained by a thorough rubbing with a No. 30 carborundum stone or an abrasive of equal quality.
This rubbing shall continue until the entire area of the surfaces is of a smooth texture ani uniform in color.
- c. During the rubbing and after final rubbing is complete, cur-ing shall proceed as herein specified.
2:05 Field Testing at Construction Site 2:05.1 During concrete placement operations, the testing laboratory will have an inspector(s) at the construction site who vill inspect the concrete pour for foruvork, reinforcing, cleanliness, and concrete placement.
The inspector shall inspect and test the first load of concrete de-livered to the site for batch ticket information, slump, air content, and temperature. Batch ticket information shall be checked on each load delivered. Slump tests will be taken at random with a msini of one test for each 10 cubic yards of concrete placed. Air content tests and temperatures shall be taken on every 50 cubic yards placed or at the direction of the Inspector.
2:05.2 Except as noted, hereinafter, test cylinders will be molded, cured, stored, capped, and teited in accordance with ACI 301-66. A set of 4 cylinders shoalle ct".t for each 50 cubic yards or fraction thereof placed in any one dty. Two cylinders shall be tested at 7 days and two at 2 8 days. . or the reactor building shell, a set of 6 cylinders s be cast. Two cylinders will be tested at 7 days, 28 days, and 90 days.
2:05.3 In the event that concrete is placed during freezing weather or that a freeze is expected during the curing period, an additional cylinder will be cast for each set and shall be cured under the sae conditions as the part of the structure which it represents. This cylinder shall be tested at 28 days.

.- *present design nix called for 7.50 bags of Ty-pe II Cement per batch.
Since the actual cement content in the production concrete was stated to be 8 bags, a slighlt change in the water centent'for slump control wilno sinificantly change the design /rti.,sfnashet "same-conditions exist in future concrete deliveries, we have no objec-tion to apply the same acceptance criteria for slump.
.In reard to temperature, we suggest that every effort shall be made jto keep the concrete temperature as low* as possible.. However, we will accept 750 F temperature as a maximum criteria for acceptance of con-crete.

Z-00-0047 Purpose The purpose of this calculation is to determine the in-place strength of concrete for use in evaluating concrete anchor spacing issues. This calculation applies to major Class I structures with the exception of the Emergency Feedwater Tank Enclosure and Diesel Driven Emergency Feedwater Pump Enclosure.
I1. Results'/ Conclusions A statistical evaluation of concrete test cylinder results for Class 3000 concrete was performed in accordance with current American Concrete Institute codes and standards to determine the as-placed concrete compressive strength. Samples of test cylinder data were evaluated to determine the concrete strength gain due to short term curing/aging. The CR3 test data was compared to long-term aging research to determine the magnitude of strength gain due to aging at CR3. All of the previous factors were combined to determine the in-place concrete strength at CR3.
The in-place compressive strength for concrete in Class I structures is as shown below. Exception areas for Class 3000 concrete are shown in Attachment J. There are several areas where 'Class 3000 concrete was specified on the structural drawings, but Class, 5000 concrete was actually placed. Those areas can be identified through review of Attachment B. The Class 5000 in-place compressive strength value can be used in those areas for evaluation of. local effects, such as concrete. anchor spacing violations.
.Class 3000 (other than in exception areas) 5460 psi Class 3000 in exception areas 4860 psi Class 5000 6720 psi

No active CR3 plant drawings relating the Pour designations used in the construction records to specific plant locations were located. Many of the Pours have sketches in the microfiche records, and there are references to "CR3-S" series drawings that were not-retained after construction.
Design Strength of Concrete (Refs. 1, 2, & 3)
- The specified 28-day design strength for Class I Structures is as follows:
Containment & Containment Interior Structures 5000 psi except Floors at El 119 & 160 and Elevator 3000 psi All other Class I Structures 3000 psi
- Class I Structures are as defined in the EDBDs (Refs. 1, 2,& 3) e Type II cement was specified for all structural concrete (Ref. 4)
- Concrete testing was performed in accordance with ACI 301-66 (Ref. 4, SP-5569).
- Concrete design was performed in accordance with ACI 318-63 (Refs. 1, 2, & 3)
IV. Assumptions None requiring later verification
, The average compressive strength and standard deviation statisti-cs" calIculated* were "based" 'on"the results of individual cylinder break results, rather than the average of two cylinder break tests. =
- This was done for convenience because the construction data for CR3 had a few pours with only :
one valid cylinder break. The effect on average strength in insignificant for populations of :
- sufficient size. The effect of this methodology on the standard deviation of the population being :
- evaluated is conservative, because it always results in a larger value for the standard deviation. -
- However, for large sample sizes the difference in standard deviation is small and does not effect _
the results of this evaluation.

VI. Detailed Calculations
Background
The compressive strength of concrete increases with age if moisture is present. Strength increases have been.documented for aging up to 50 years, generally following a logarithmic curve (Ref. 12). At early ages, higher-strength concrete shows a higher rate of strength gain (in terms of absolute strength) as compared to lower-strength concrete. However, after approximately 95 days the differences in normalized strength gain are not significant (Ref. 11). When normalized to 90-day compressive strength, typical concrete made from Type II cement shows a strength gain of approximately 25% after 5 years (Ref. 7, Fig. 6.1).
Variations in strength test results are due to differences in the strength-producing properties of the concrete mixture and ingredients, and apparent differences due to variations inherent in testing. It is well established that concrete strength is governed to a large extent by the water-cement ratio. The results of concrete cylinder tests for a specific mix design produced over time with good quality control are expected to fall into a pattern similar to the normal frequency distribution curve. (Ref. 5)
The required average compressive strength f'cr to be used for selection of a concrete mix is the larger of the following (ACI 318-89 5.3.2.1 & ACI 349-90 4.3.2.1):
f'cr =f'C + 1.34 s or fcr C +2.33s-500 where Vc is the specified design compressive strength, and s is the standard deviation of the compressive strength test results. These equations provide a probability of about 1 % that the averages of 3 consecutive strength test results will be below the specified f't, and a similar probability that any individual test will be more than 500 psi below the specified compressive strength. The standard deviation s is to be determined from a minimum of 30 tests. However, 100 tests. are recommended. Each test is the average of at least 2 cylinders made from the same batch of concrete, cured under the same conditions, and tested at the same age (Ref. 6).
The strength level of an individual class of concrete is considered satisfactory if both of the following requirements are met (ACI 318-89 5.6.2.3 & ACI 349-90 4.7.2.3):
(a) average of all sets of three consecutive strength tests > f'c and (b) no individual strength test (average of two cylinders) < (f'c - 500 psi)

Although several different mixes were used for the Class 5000 concrete, the materials used were the same as the Class 3000 concrete. Type II cement was used to minimize heat development and the subsequent volume changes and cracking during hydration of the cement. All of the structural concrete used the same admixtures (Darex and Daratard)., The major difference between the Class 3000 and Class 5000 concrete mixes are the water-cement ratio.
The concrete mixes most often used for Class I concrete at CR3 are as follows:

Cursory review: indicates that the mix modifications were to the: cement factor (bag/cu yd), and that water-cement ratios were held constant. Since the water-cement ratio is the single most important factor influencing concrete strength,* any minor effects on compressive strength and the'rate of strength gain due to the mix modifications are not considered in this calculation. A mix designation as used, in this calculation includes all modifications of the mix.
This calculation will evaluate two different aspects of concrete strength at CR3:
- 1. Long-term strength gain for Class 3000. and. Class 5000 concrete
- a. 28 to 90-day strength gain
- b. Post 90-day strength gain
- c. Discussion of conservatism
- 2. As-placed concrete strength for Class 3000 concrete
- .h ibit 8 Page 7 of 19 Power DESIGN ANALYSIS/CALCULATION Crystal River Unit 3 DESA-.FRM Page 7 of 24 DOCUMENT IDENTIFICATION NO. N S-00-0047 0 The specified compressive strengths for concrete at CR3 were 28-day strengths. For the purposes of this. calculation, long-term strength gains are considered as those occurring after 28 days. The strength gain over a time increment will be determined as ratio fcT / fcTO . The use of the ratio essentially normalizes the data, and breaks the strength vs. time curve into linear segments.
Ample data exists for Class 5000 concrete to determine the 28-day and 90-day average compressive strengths from statistically significant samples. Class 3000 concrete has only limited 90-day test data, which will be evaluated to determine its validity. Strength gains from 7 to 28 to 90 days for the limited data set will be compared to 7 to 28 day strength gains for a statistically significant sample of Class 3000 cylinder test data.
There is no test data for CR3 concrete past 90 days. Strength gains past 90 days will be conservatively estimated by comparison of CR3 concrete to research presented in the literature.
Concrete mixes are conservatively designed to exceed the compressive strength required, due to the inherent strength variations of the as-placed mixture caused by a many conditions that vary in the field. The ACl codes recognize the potential for strength variations, and specify the margin required for a concrete mix design. The codes allow for a statistically small amount of concrete that may be less than the specified design strength. If good quality control is used during construction, the concrete placed may be significantly stronger than required by the design specifications.
For calculations where concrete strength is a critical factor, such as for anchor spacing evaluations, there is a large benefit to taking advantage of higher concrete strengths.
Therefore, the 28-day test data for Class 3000 concrete placed for the Class I structures of interest will be reviewed to determine the strength of concrete that was actually placed. A statistical evaluation of the data will be performed and each set of data will be checked against the ACI compressive strength acceptability criteria previously discussed.
Sufficient data also exists to determine the as-placed compressive strength for Class 5000 concrete. However, due to the effort required to retrieve the test data and the already higher specified strength, the evaluation is not warranted for Class 5000 concrete.
In order to evaluate the concrete used in Class I structures at CR3, the concrete pour records were reviewed. The structures of interest are primarily the RB, AB, CC, IB, and DGB, since those buildings are where the vast majority of safety related concrete anchorages are located. Concrete pours for Berm Protection (wave steps) and Hurricane Protection walls were included in the review only to the extent that test data from those pours was relevant to the structures of interest. Also note that only the east side of the Intake Structure is considered Class I.
The concrete pours for the buildings of interest were generally numbered in sequential order, with a suffix indicating the building or structure. The pour records reviewed generally have a pour slip with data about the pour, truck slips and QC reports, usually a sketch showing the specific pour location, and test data for test cylinders associated with the pour.

The location description and elevations shown for the top of the pour should be considered reference only; for specific details the pour records should be consulted.
Attachment B shows concrete pours generally grouped by building and location. Again, the descriptions used for the list are not precise and the construction records should .be consulted for specific details.
Long-term Strength Gain A. 28.to 90-Day Strength Gain The specified concrete strengths for concrete at CR3 were 28-day strengths. Class 5000 concrete generally had test cylinders broken at 7, 28, and 90 days. The Class 3000 concrete generally had only 7 and 28 day test cylinders. However, two sets of test cylinders for Mix T-21510 (Pours 28-DHP and 29-DHP) had 90 day tests.
Test cylinder data was retrieved for approximately 100 sets of cylinders each for Mixes T-.21510, DM-5, and 727550-2. The sample size of at least 100 tests is per ACI-recommendations for determination. of compressive strength statistics. The average break strengths for the test cylinders were analyzed to determine the average strength gain from7 to 28 to, 90 days, as applicable. The data and strength. gain evaluations are presented in Attachments C, D, E, and F. The results of a statistical analysis of the test cylinder samples are show in Attachment G (Note: Statistics for.Mix T-21510 on Attachment G, Page 5 are for a larger sample discussed later).
Comparison of the two Class 5000 mixes show that they are virtually identical regarding -
strength and strength development. At 90 days the average compressive strength of the two :
mixes is within 100 psi and .the standard deviations vary by only 20 psi. The 28-day test
- results show considerable scatter when compared to the expected normal distribution, but the-normal distribution curve is a reasonably good fit for the 90-day tests (see Figures 1 & 2).:
From 28 to 90 days, the standard deviations of both samples decreased significantly. This is :
- possibly an indication of differences due to curing rates or modifications to the mix, and that those differences are not significant after 90 days. The apparent variations.from the norm due to testing technique would not be expected to change according to test cylinder age.

______ 90 .5805 1.34 Although the .differences between the two Class 5000 concrete mixes are not statistically significant, the strength gain from 28 days to 90 days will be conservatively considered to follow the Mix 727550-2 curve due to its slightly flatter slope. The. gain from 28 days to 90 days for'Class 5000 concrete is 12%.
Comparison of the data for Mix T-21510 from Attachment C to the data from the two pours in the Decay Heat Pit (Attachment F) for the same concrete mix leads to the conclusion that Pours 28-DHP and 29-DHP are representative of all of the.Class 3000 concrete. The strength gain from 7 to 28 days is parallel for both samples, so a projection of the T-21510 sample' average compressive strength at 28 days out to a 90-day compressive strength based on the two DHP pours is justified. A conservative straight-line extrapolation of the T-21510 data would give a 90-day compressive strength .of approximately 5900 psi, as shown on Figure 3.
That is equivalent to a gain from 28 days to 90 days of (5900 - 4535) / 4535 = 30%
The straight line extrapolation is considered conservative because it results in. lower gain ratio than the data from the two DHP pours.

10N S-OM-047 B. Post 90-Day Strength Gain The rate of compressive strength gain for a' typical concrete made from Type II cement is shown in ACI 225R-91 Fig. 6.1 (Ref. 7):

The error is apparent if the data is plotted to scale. The "Concrete Construction Handbook" (Ref. 12) presents the same graph. showing the data at 5 years.,
The comparison of the three CR3 mixes to .the typical Type II.curve is shown in Figure 4. All of the CR3, mixes have a higher rate of strength gain: from 28 ,days to 90 days than the ACI curve. The CR3 concrete mixes are higher strength than the typical Type II data.
Higher-strength concrete would be expected to gain strength more quickly than lower strength concrete. The use of admixtures could also affect the rate of strength gain. Therefore, deviations of sample data from the typical curve would be expected, but differences might be expected to diminish with time. After, 90 days the strength gain due to aging should be similar for concretes made from. the same type of cement. This would be indicatedon a graph such as Figure 4 by parallel lines. More scatter would be expected for data from early ages, with a trend toward more consistency with increasing time.

REMVSION S-00-O047 0 To eliminate the effects of different design compressive strengths on the comparison, the data has been normalized to 90 days and replotted in Figure 5. The data as presented in this format show a reasonable agreement with the typical Type II curve when consideration is given to the higher early strength gain expected for higher strength mixes. Although the data, by definition, converge at 90 days due to normalization, the trend agrees with the typical Type II cement curve.
The typical Type II cement curve from ACI shows a strength gain from 90 days to 5 years of 25%. A conservative extrapolation of the data from the CR3 mixes past 90 days, giving consideration to the decreasing slope of the strength gain curve, leads to the conclusion that a 20% strength gain from 90 days to 5 years could reasonably be expected for CR3 concrete.
Concrete strength gains due to aging have been documented to occur out to 50 years.
However, after about 5 years the strength gains become small and relevant data in the literature was not located. Neglecting strength gains that may occur after 5 years is conservative. The earliest Class I concrete pours at CR3 were started in June 1970. The major structural elements were completed by early 1976. Given the age of the CR3 concrete, a strength gain of 20% from 90 days to the present would appear to be a conservative projection, based on the supporting data.

REVSN S-OO-0047 C Discussion of Conservatism The compressive strength, vs. time curve for concrete has:been approximated by straight line segments on a: semi-logarithmic graph. Based on existing test data, extrapolations, and comparison with typical concrete aging data in the literature, the slopes of the line segments (or "gain ratios") have been conservatively determined. For the purposes of this calculation, a conservative gain ratio is one that results in, a lower compressive strength. The conservatism for each gain ratio has -been previously discussed.
The strength vs. time curve that is represented by the line segments describes the behavior of average compressive strength (designated as fc Avg )* The CR3 cylinder test data and the typical Type II cement curve from which the gain ratios were determined use average concrete strength from cylinder compression tests.
ACI codes require that concrete mixes be selected such that the average compressive strength required fcr) exceeds the compressive strength used for design (W'e ) This is done so that only a statistically small amount of concrete would be expected to be understrength.
The margin required is related to the standard deviation "s" of the results of a population of cylinder tests for the proposed mix. The more restrictive of the following two requirements applies: f'cr = f c +1.34 s or f'r = f+ + 2.33 s - 500 If the standard deviation of the selected mix is known and assumed to remain constant for jobs with good quality control, then the margin required for both requirements above is essentially a multiple of s. For simplicity, the margin will be considered as 1.34 s for the remainder of this discussion.
After concrete has been placed and cylinder tests have been completed, fc Avg and s are known. The maximum design compressive strength that can be credited can be found by rearranging the equation, using fc Avg for f'c,:
f'e =fc Avg -1.34 s

Typically the design strength f' for concrete is specified at 28 days. If strength is predicted using "gain ratios" the long-term design derived from average strength. data, conservative because of the. 1.34 s the result will be term in the above equation.
Consider the following example, for a concrete with 28-day test results and s = 500 psi (s assumed constant of 1c Avg - 5670 psi over time). The 28-day, design strength calculated as is back-f'c 5670 - 1.34 x 500 = 5000 psi In the table below, the 90-day and 5-year values of fc Avg and f'c are predicted ratio's shown, and the third column is using the gain calculated from fc Avg and the constant s.

the design compressive strength that utilized is represented by the line could be parallel to the average strength 'curve, (1.34 x s) less than the average and is always strength. The predicted f'c curve is difference becomes greater if larger gain always lower, and the ratios are utilized for any line segment.
90-day gain ratio for Class 3000 concrete Note that the 28 to was determined to be 1..30.
The discussion above has considered that the standard deviation is constant noted previously when evaluating the over time. As test result sample population statistics concrete, the standard deviations decreased for Class 5000 significantly between 28 and 90 days.
reasonable as small differences in curing This is rates would. be expected to diminish the sample population would therefore with time, and.
become more uniform, If s decreases the term (1.34 x s) also decreases, which with time then results in a larger difference (more conservative) the predicted design.compressive strength between and the maximum value that could be utilized.
Summarizing the discussion above:
Use of the conservative average compressive strength "gain ratios" to predict design strength results in even more long term conservatism.
