Fig. 2. Studied schemes and dimensions of test samples: ( а ) the experimental sample for compression of the cube; (b) the experimental sample for compression of the prisms; (c) the experimental sample for tensile prisms; ( 1 – cube experimental sample; 2 – prisms experimental sample; 3 – prisms experimental sample; 4 – lower and upper traverse of the hydraulic installation PG-250; 5 – tensor resistors; 6 – watch-type indicators with 0.001mm graduations on a 400 mm base; 7 – fixing indicators in the form of steel frames; 8 – special built-in anchor devices that allowed testing prisms for tension). Tensile testing of the samples for the second series was performed on the UMM - 50 tensile test unit. The prisms were tested with a one - time static load till failure.
