Field Device to Measure Viscosity, Density, and Other Slurry Properties in Drilled Shafts

The primary objective of this study is to develop equipment capable of determining the insitu slurry properties in drilled shaft excavations. As present methods recover samples manually on 10ft depth centers for top side testing, the envisioned system will take continuous measurements of density and viscosity as it is lowered. This is particularly advantageous for early evaluation of the slurry health. More important are the slurry properties prior to concreting where the sand content must also be determined. In these cases, discrete sampling may be necessary and is suggested as a minimum level of acceptability with regards to the successful system development. The overall approach to the study incorporates several work tasks that largely explore existing sensor technologies with the goal of adapting them to the needs of this system.
