The article describes the experimental studies into hydraulic fracturing of thick-walled cylinders with a circular hole and made of cement-based GF-177 mixture. Limiting stresses are determined in four types of stress state of the bodies: uniaxial compression and tension, Brazilian Test and hydraulic fracturing. The data of the Brazilian Test and compression of rectangular parallelepipeds and circular cylinders were used to determine limiting pressure in hydraulic fracturing. The critical stress intensity factor is found. The calculated limiting pressures are compared with the values found analytically from the Lamé solution and with the test data. The influence of the storage interval on the strength is described.
