The results of comparing tests on adhesion of sand-cement mixture, produced on the base of different grades of cement immediately after pulse electromagnetic treatment, after 72 hour after treatment (experimental solutions) and without treatment (control solution) have been presented. The essential increasing of adhesion of experimental solutions on the base of PTs 400 (Russian grades) cement, compare with control solutions, and insignificant increasing of adhesion of solutions on the base of more higher-grades cement have been defined.
