In-line rheometry of micro cement based grouts . a promising new industrial application of the ultrasound based UVP+PD method

Measurements of the viscosity of non-Newtonian fluids and suspensions having a solid volume fraction of about 30% or
more is of major interest from an industrial point of view. Cement paste and cement grouts for injection grouting applications,
with water to cement ratios typically in the range of 0.4 and 0.6 - 0.8 by weight, are two examples of industrial fluid
systems. Few in-line techniques are available on the market that can be used for these fluid systems and under realistic field
conditions. The so-called UVP+PD in-line rheometry method combining the Ultrasound Velocity Profiling (UVP) technique
with Pressure Difference (PD) measurements is a promising new tool for industrial applications. This paper presents an initial
pre-study that aims to demonstrate the feasibility of the UVP+PD method using cement grouts for process monitoring and
control of grouting applications under realistic field conditions. The UVP+PD method was tested and found successful for
continuous in-line measurements of concentrated micro cement-based grouts with water/cement ratios of 0.6 and 0.8. The
test set-up consisted of a combination of an experimental .flow loop. and a conventional field grouting rig - UNIGROUT, from
Atlas Copco. The rheological properties were determined, directly in-line and the parameters obtained were subsequently
compared with off-line measurements using a conventional rotational rheometer.
