. MATERIALS AND CONCRETE CONSULTANTS 011 SKOKIE BOULEVARD 13121 272-7730 NORTHBROOK. ILLINOIS 60062 STUDIES OF CONCRETE AND COARSE AGGREGATE FROM THE DOME OF THE CRYSTAL RIVER UNIT #3 REACTOR FOR CONSTRUCTION ENGINEERING CONSULTANTS
SUMMARY
AND DISCUSSION The aggregate was a crushed, fine-grained limestone. About one-half of the particles were dense and firm; the remaining one-half were fossiliferous, contained shell frag-ments, were generally porous, and had a chalky texture.
Dolomite was not. dotected. The acid in-soluble residue content was 2.2 percent and cbnsisted of cla s a major cm Ant __
quartz as a minor component. The aggregate contained less than 0.1 percent clay lumps by weight.
Individual particles were generally equi-axial, and angular. All particles were dusty due to crusher fines that adhered to surface irregularities. The clay lumps will degrade during mixing.
The results of the chemical test for alkali-silica reactivity of the aggregate were neg-ative. Thus the aggregate is classed as
- non-reactive.

F'M 5.1 Exhibit 6b Page 2 of 4 ERLIN, HIME ASSOCIATES MATERIALS ANO CONCRETE CONSULTANTS The core represented air-entrained concrete, very well proportioned and. fabricated, and made with physically and chemically sound aggregates.
On the end of the core that represented a delaminated face were sevondary deposits of ettringite and calcite. The ettringite was present in voids located in a 3/16 inch thick zone at that end of the core. The sec-ondary deposits demonstrate that the concrete at that end of the core had been exposed to moisture for prolonged periods. Because of the density of the paste (a result of the use of a low water-cement ratio) an exposure up-wards of one year is probable.
In summary, the concrete was very well made and did not evidence any volume instability fea-tures due to chemical or physical changes of components. That was confirmed with respect to the coarse aggregate by separate studies of the coarse aggregate. One end of the con-crete had been exposed to moisture for periods judged to be upwards of one year.
INTRODUCTION Reported herein are the results of petrographic studies of a concrete core and a separate coarse aggregate spec-imen, and the chemical method for evaluating the potential alkali-silica reactivity of the aggregate specimen.
The studies were requested by J. Artuso of Construction Engineering Consultants in conjunction with concrete of the Florida Power Corporation Crystal River, Unit
- 3 Dome.
STUDIES Specimens- Received for the studies were: (1) a core identified as No. 8B-3 and representing concrete near the apex of the dome (one end of the core was the sur-face of a delamination face); and (2) coarse aggregate used for the construction.
Petrographic Studies (Aggregate) - The studies were made in accordance with the procedures given in ASTM Desig-nation: C295, "Petrographic Examination of Aggregates For Concrete" and Erlin, Hime Associates Quality Control Procedures For Nuclear Power Projects-.

F'M 5.1 Exhibit 6b Page 3 of 4 ERLIN, HIME ASSOCIATES MATERIALS AND CONCRETE CONSULTANTS The aggregate was a gray-white, crushed, fine-grained, massive textured, imum nominal fossiliferous size was 3/4 inch. limestone.
The aggregate The contain-max-ed clay lumps; however, the clay constituted less than 0.1 percent, by weight, of the total aggregate.
Approximately one-half of the limestone was fossiliferous.
These particles were generally more porous and many con-tained small vugs. The remaining limestone was hard and dense. The clay lumps were soft and friable. Many con-tained shell fragments. These particles will probably degrade during mixing.
The calcite/dolomite ratio, determined by X-ray dif-fraction methods was 1:0 (dolomite was not detected.)
The acid-insoluble residue content was 2.2 percent. The residue consisted of clay as a major component and quartz as a minor component. Opaline material was not detected.
Particles were generally equi-axial and angular. Broken edges were sharp, or frequently rounded due to attrition during processing. The aggregate was dusty due to crusher fines that adhered to surface irregularities.
The aggregate should be washed prior to use.
Quick Chemical Test - The aggregate'was tested for alkali-silica reactivity in accordance with the procedures in A'STM Designation: C289, "Potential Reactivity of Aggre-gates (Chemical Method)".
Test results are given below.
Rc 37 millimoles per liter.
$c 19 millimoles per liter.
The test data indicates the aggregate to be innocuous.
Petrographic Studies (Concrete) - The core had a diameter of 3 5/8 inches and a length of 5t inches.
The coarse aggregate of the core was as described in the section covering the petrographic examination of the aggre-gate. The fine-aggregate was a siliceous sand consti-tuted principally of quartz.
The aggregates were poorly graded as demonstrated by deficiencies of the finer sizes of the coarse aggregate and the coarse sizes of the sand.
There was no evidence that the aggregate had been either physically or chemically unsound. Not detected were alkali reactive materials such as chert and opal, or reaction products of chemically unstable aggregates.

rM 5.1 Exhibit 6b Page 4 of 4 ERLIN, HIME ASSOCIATES MATERIALS AND CONCRETE CONSULTANTS Paste was medium dark gray, firm, and contained abun-dant residual and relict cement. The compositional and textural characteristics of the paste are indicative of a low water-cement ratio.
Air in the core occurred as small, discrete, spherical voids characteristic of air purposefully entrained, and as coarser non-spherical voids characteristic of entrap-ped air. The air content of the core is estimated to be 5J percent and the parameters of the air-void system are judged to be effective for protecting critically saturated concrete exposed to cyclic freezing.
On one of the ends of the core, and in a 3/16 inch zone at that end, were secondary deposits of acicular ettring-ite (3CaO;Al 2O0 3CaSO4 -31H 2 O) that lined samll surface areas on the ead and some of the air voids in the 3/16 inch zone. Secondary calcite (CaCO3) was associated with the ettringite on the end of the core. These secondary deposits demonstrate that the concrete portion asso-ciated with the ettringite had been exposed to moisture for prolonged periods.
