Annotation:

The article presents the results of laboratory tests of shotcrete specimens on tensile bending. Prototypes are pre-destructed and recovered specimens with surfaces glued with PVA emulsion. Control samples are standard samples, which are used to carry out the comparative analysis of the test results. The article presents the diagrams of strain deflection from the load for experimental and control samples. The strength limits of the samples on tensile bending are defined.
