MEMORANDUM

To: Jie Yu, Civil Engineer

Geotechnical Engineering 2 (86-68312)

From: Blake Armstrong, Civil Engineer

Concrete, Geotechnical, and Structural Laboratory (86-68530)

Subject: Transmittal of TM No. 8530-2018-54: Results of Soil Testing on Heart Butte Dam

Conduit Material; Pick-Sloan Missouri basin Program, Heart Butte Dam, ND

Material was collected the conduit at Heart Butte Dam and delivered to the Technical Service

Center’s (TSC) Concrete, Geotechnical, and Structural Laboratory (CGSL). The following tests were conducted on this material: water content, dry unit weight, physical properties, direct shear, reaction to HCl, and X-ray diffraction (XRD). Microscopic photos were also taken.

Borrow material was collected from three test pits at Heart Butte Dam and delivered to the

TSC’s CGSL. Material was tested for physical properties, and one sample was tested for maximum dry unit weight and optimum water content.

Conduit material was non-plastic SM – silty sand to SP-SM – poorly graded sand with silt.

Some gravel samples had strong reactions to HCl. Direct shear test results indicated an internal friction angle of 39.4° and cohesion of 292 pounds per square feet (psf). XRD analysis indicated mainly quartz and clays (smectite and illite).

Borrow material was classified as SM – silty sand. Maximum dry unit weight and optimum water content in test pit TP-18-1 was equal to 130.5 pounds per cubic feet (pcf) and 11.2 %, respectively.

If you have any questions, or if you would like hard copies of this report, please contact Blake

Armstrong at 303-445-2027 or via email at barmstrong@usbr.gov.

Notes:

1) Natural Moisture/Unit Weight to be determined for individual direct shear test speicmens. Bag samples will be tested for as-received water content only.

2) Tube Density determinations will be performed on intact material in tubes before preparation of direct shear specimens

3) Some samples have limited amount of material. Physical property testing will be performed with the following priority: gradation, Atterberg limits, hydrometer, specific gravity.

Heart Butte Samples: BADS-01, -02, -03, and -04 Semi-Quantitative Weight Percent Mineralogy and Clay Mineral Identification by XRD Audrey Rager July 30, 2018

Semi-Quantitative Weight Percent Mineralogy by X-Ray Diffraction

The identification of minerals contained in four (4) samples from Heart Butte, were obtained by X-ray powder diffraction (XRD) analysis. The samples were crushed in a Fritsch mortar grinder pulverisette 2 from which the <45 m size fraction was subject to XRD analysis. The analyses were carried out in a powder diffractometer using Cu radiation (45kV,40mA). No elemental data were provided for the three sand samples.

X-ray diffraction scans were collected on a PANalytical X’Pert Pro MPD diffractometer with Bragg Bertano optics using copper radiation. Scans were collected from 4 to 80 degrees two-theta at a rate of 1 degree per minute.

Identification of mineral phases was performed using Material Data Inc. (MDI) Jade (V 9.6) search-match software using the ICDD’s “2014 PDF-4” and National Institute Standards and Technology “FIZ/NIST Inorganic ICSD” databases. Semi-quantitative mineral estimates were calculated using MDI Whole Pattern Fit software which simultaneously calculates a whole pattern fit and a Rietveld refinement of the minerals. Clay minerals were identified according to procedures outlined in U.S. Geological Survey Open-File Report 01-041.

The samples were provided to the Petro Lab in plastic sample bags with descriptions (Table 1). Samples ID numbers were assigned to the four samples as shown in Table 1.
