Due to the natural heterogeneity of rock there exists a large variance between samples in geomechanical engineering testing. Additionally, the number of samples available for testing that meet the screening requirements for grain size, mineralogy, bedding orientation and moisture content can...

High-Float Emulsion Residue: A New Rheological Model Based on the Existence of a Yield Stress
DownloadFall 2016
“High-float” (HF) emulsions are dispersions of micron-sized bitumen droplets in water, with a special type of anionic surfactant functioning as stabilizer. By allowing the water to evaporate from an HF emulsion, what remains is called a “high-float emulsion residue.” Although indistinguishable in...

The addition of coarse particles to a flocculating fine particle slurry increases the Bingham yield stress of the resulting mixture, which can drastically alter the laminar-to-turbulent transition velocity. The objective of this study is to quantify the effect of coarse particle size and volume...
