Description:

Abstract:

The safety, effectiveness and longevity of many construction and geotechnical engineering projects rely on correctly accounting for the evolution of soil properties over time. Critical sediment properties, such as compressibility, can change in response to pore-fluid chemistry changes, particularly if the sediment contains appreciable concentrations of fine-grained materials. Pore-fluid changes act at the micro scale, altering interactions between sediment particles, or between sediment particles and the pore fluid. These micro-scale alterations change how sediment fabrics and void ratios develop, which directly impacts macro-scale properties such as sediment compressibility. The goal of this study is to correlate sediment compressibility, a macro-scale property, to the micro-scale pore-fluid chemistry effects and ultimately to the electrical sensitivity for each sediment. Such a correlation would allow compressibility behavior to be estimated from knowledge of the index properties and mineralogy profile for each sediment. The data in this release support the correlation effort by providing: 1) sedimentation results that provide insight into micro-scale sediment fabric and void ratio dependence on sediment/fluid interactions, and 2) consolidation results that quantify the macro-scale compressibility and recompressibility parameters for a suite of fine-grained sediments and differing pore fluids. The related journal publication (Jang and others, 2018) demonstrates how the macro-scale compressibility and recompressibility results from the consolidation tests are linked back, through the sediment fabric and void ratio data from the sedimentation tests, to the micro-scale impact of pore-fluid chemistry and sediment electrical sensitivity.

Purpose:

Consolidation data provide the macro-scale expression of a set of micro-scale interactions between fine-grained particles and between those particles and the pore fluid surrounding them. These data support an effort to connect the micro- and macro-scale sediment response to changes in pore fluid chemistry. Data contained in this report cover a suite of fine-grained sediment types and pore fluid chemistries to provide trends for interpreting sediment compressibility over a range of environments, applications and system-evolution scenarios. Specifically, the consolidation data are used to build a correlation with a sediment index property (electrical sensitivity, which is based on the liquid limit of each sediment). The correlation is presented in the related journal article (Jang and others, 2018).

Data_Quality_Information:

Logical_Consistency_Report:

The sediment used in these experiments were purchased rather than acquired through a field activity, so there is very little specimen-to-specimen variation for a given sediment. Sediment was shared between the two participating laboratories as described in the first process step, so each laboratory ran using sediment from the same batch. Pore fluid preparations were made in the same fashion each time, and the specimen set-up procedure always used the same initial fluid saturation. All tests were run on the same type of oedometer with the same number of loading/unloading steps. The major variation between runs is the pairing of a particular sediment with a particular pore fluid, and investigating that variation is the purpose of the larger study these data support.

Completeness_Report:

All 21 combinations of the 7 sediment types and 3 pore fluids were tested. Because small variations in the applied vertical stress for the oedometer could occur from one run to the next, the data are laid out in the spreadsheet assuming the applied vertical stress is unique to each run. This means each data row represents just one step in one experiment for a given pairing of sediment and pore fluid. For a given row, there are blanks in two of the three void ratio data columns, indicating the pore fluids associated with those data columns were not used in that particular test.

Process_Description:

Specimen set-up:
The specimen setup process is imaged in the browse graphic: (A) sediment from one of the seven tested sediment types was mixed with one of the three tested pore fluids. The specimen was mixed with enough water to attain a fluid content of 1.2 times the liquid limit (liquid limit values provided in Table 1 of the related journal article publication (Jang and others, 2018) linked to this data release) and allowed to stabilize for 12 hours. This fluid content ensures the sediment is fully saturated with pore fluid. (B) The sediment-fluid mixture was placed into a Geotac 2.5 inch, 1-dimensional fixed-ring consolidometer, and (C, D) loaded into the Geotac load frame with additional water added above the specimen to ensure it would remain fully saturated for the entire test. Tests were completed at the U.S. Geological Survey in Woods Hole, MA (USGS) by Junbong Jang, and also at Louisiana State University in Baton Rouge, LA (LSU) by Shuang Cao. The two sites used identical Geotac 2.5 inch, 1-dimensional fixed-ring consolidometers. Sediment used in this study was purchased and delivered to the USGS in Woods Hole, where sediment splits were generated and shipped to LSU for testing. Only the specimen height differed between the two laboratories: USGS specimen height = 25.4 mm; LSU specimen height = 19.05 mm. Junbong Jang is the long-term contact for questions regarding results derived in either laboratory.

Process_Step:

Process_Description:

Measurement: Consolidation measurements were run according to American Society for Testing and Materials standard D2435 [ASTM, 2011]. The applied vertical stress schedule was: 1) loading from 20 to 1280 kPa, doubling the load with each step; 2) unloading at 640, 160 and 40 kPa; 3) reloading from 80 to 1280 kPa, again doubling the loading stress at each step. Vertical stress measurements, taken from a load cell above the consolidometer, had a precision of ± 0.05 kPa. Void ratio measurements were made based on the specimen height (tracked continuously with a linear voltage displacement transducer) at a given vertical stress step, and calculated according to the derivation in ASTM D2435 [ASTM, 2011]. Void ratio results had a precision of ± 0.0005 [unitless]. Tests were completed at the U.S. Geological Survey in Woods Hole, MA (USGS) by Junbong Jang, and also at the Louisiana State University in Baton Rouge, LA (LSU) by Shuang Cao, both according to ASTM-D2435 [ASTM, 2011]. Junbong Jang is the long-term contact for questions regarding results derived in either laboratory.
