Today there are stricter environmental demands, focus on cost optimization and control of waste levels. The properties of cement grouts significantly influence the flow behavior during the grouting process, and consequently the final spread and sealing effect that can be achieved in grouted rock formations.

Cement grout quality tests are normally carried out with old tools/methods such as flow cups and marsh funnels. These tools rely on operators, are time-consuming and tests are done under different conditions which provides limited data on pipe flow. It is therefore important to monitor and control these essential flow properties in line during the grouting process, ensuring a standardized and more sustainable method for controlling the grouting operation.
