Despite the numerous backfill systems applied, the main isolation material used currently in various repair-isolation works are the cement suspensions on different bases. It predetermines the necessity of consideration of rheophysical studies on mentioned systems, which will enable to specify the ways of improvement of their rheological properties and reveal the fields of efficient implementation this or that isolation system. The main purpose of rheophysical investigations is to study the deformability and flow rate of substances, define the parameters characterizing current tension and specify their dependence on various factors.

The paper justifies that a special group of rheopysical problems is associated with the development of systems, stress state of which is characterized with parameters of inner friction and adhesion as well.
