• Abstract:
  Proper performance of the mineral slurries used to stabilize drilled shaft excavations is ; maintained by assuring that the density, viscosity, pH, and sand content of the slurry stay ; within limits set by the Florida Department of Transportation (FDOT), which are derived from ; past experience, research findings and/or by manufacturer-recommended ; values. However, the repetitive slurry testing ; required in the field is a time-consuming, manual process. ; Applying modern technology to this problem could offer ; more rapid and reliable testing. ; University of South Florida researchers developed and tested ; a device that estimates slurry viscosity, density, and sand ; content within a drilled shaft excavation. The test can be ; performed at the surface; a slurry sample is not needed.
