Without additives, the immediate agent of high-strength gypsum solution thickens in 10 minutes. and sets 14–15 min.

In all the above recipes, the water-gypsum ratio is -0, 5.

The main advantages of the use of the proposed high-strength gypsum, as compared with the commonly used cement-based tamping compositions, are: a) the possibility, over a wide range, that others do not have for cutting, their materials to regulate the time of thickening and setting; b) easy penetration of plaster

solution, because of its mobility. into small cracks; c) the capacity for solidification to increase in volume (as opposed to cement solutions that shrink) and, thereby, tightly fill all cavities.

Subject invention

The use of high-strength gypsum according to All-Union Technical Specifications 33-34 for plugging the ways of leaving the mud with an additive to gypsum to retard thickening, or keratin glue in an amount from 0.025 to 0.4 of the weight of gypsum or sulfite alcohol stillage from 1 to 5%.
