The rheological properties of sealing slurries are very important when designing and executing cementing jobs and reinforcing ground and rock mass with the use of drilling technology. In order to ensure a high level of efficiency, the applied sealing slurries should meet several requirements. One of the most important criteria is pumpability. The rheological model and the rheological parameters of the sealing slurries should be properly selected to ensure efficient pumping. On this basis the flow resistance of the slurry in the circulation system can be calculated. The paper presents the results of laboratory experiments on the influence of some liquefiers on the formation of rheological properties of cement slurries used for sealing and strengthening rock mass, and for cementing jobs.
