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:
Sedimentation measurements of the patterns and rates at which particles settle in fluids of different chemical makeup yield insights into the dependence of interparticle interactions on fluid chemistry. Data contained in this report cover a suite of fine-grained material types and pore fluid chemistries to provide trends for interpreting sediment compressibility over a range of environments, applications and system-evolution scenarios. The sedimentation data is used to interpret the associated compressibility data from this data release in the related journal article (Jang and others, 2018).

Data_Quality_Information:
Logical_Consistency_Report:
The settlement tubes used in this work were all cut from the same acrylic tube, and thus are all of the same diameter. Equal heights of sediment and liquid were used in each test, and agitation times prior to allowing the system to settle were equivalent.
Completeness_Report:
Not all sediment types were measured in every fluid, so not all spreadsheet columns contain data for each sediment. Blank interface height entries within a column of measured data occur for one of two reasons: either the interface height in question could not be resolved at the stated measurement time, or that particular measurement time was not utilized for the given sediment-fluid pairing.

Process_Description:
Specimen set-up:
After oven-drying one of the seven sediment types, sediment was spooned into a 25.4 mm diameter acrylic settling tube (settling tube pictured in the browse graphic). Gentle spooning of sediment into the settling tube created a loose-packed (maximum void ratio) fabric with a sediment height of 25.4 mm. The sediment was then mixed with a one of the test fluids to a final height of 152.4 mm to obtain a ratio of one to six in the diameter to height of the fluid column. The mixture was allowed to stabilize for more than twelve hours before the cylinder was evacuated in order to remove gas from the fluid. After degassing the fluid, the headspace was reopened to the atmosphere momentarily before a new stopper was inserted into the cylinder top to seal the specimen and water for the duration of the test. The sealed cylinder was shaken for one minute before being left to settle undisturbed.

Process_Description:
Measurement: Heights of the depositional interface and the accumulated sediment interface were measured as functions of time until the interface locations stabilized (one to four days, see Browse Graphic for example of sedimentation behavior). Measurement intervals increased with time in an approximately logarithmic fashion over the course of a complete test to capture time-varying behavior of the sedimentation. Time measurements were made with a stopwatch, and had a precision of ± 0.2 min. Height measurements were made with a ruler affixed to the cylinder, and had a precision of ± 0.1 mm.

Process_Description:
Version 1.1: results have been added from additional testing done on diatoms since the release of Version 1.0. In Version 1.0, the diatom sediment type was not measured in each of the pore fluids used in this study. Version 1.1 includes the Version 1.0 results, with the addition of diatom results for sedimentation in brine concentrations of 1mM, 10mM, 100mM, 600mM and 1M, and for diatom sedimentation in the dispersant, Hexametaphosphate. Measurements were made according to the process steps listed for Version 1.0, and blank entries indicate no measurement was made at the given time for the given pairing of sediment and fluid. For the added diatom data, three additional time intervals (1125, 1860 and 4320 seconds) were utilized for certain fluids. To reflect new data results, the Range Domain values in the Attribute metadata below were updated as necessary.
