Summary: | A method for preparing a plugging material of an alumina-base cement, by mechanical stirring of alumina cement with additives of the pre-rated quantities to improve the physical and mechanical characteristics of the plugging material. The stirring is effected by magnetized working bodies in an alternating electromagnetic field. The resultant material is subjected to a batch forming by compression at a pressure between 50 and 120 MN/m2. |
