Based on the series of tests for three-point bending of rectangular bars with central cuts on a universal test machine, using the compliance and K-methods, experimental values of the fracture toughness characteristics of the material under investigation were obtained. In this work, the characteristics of the fracture resistance of casting artificial stone (CAS) were determined. The obtained values of the mechanical characteristics of the material are comparable to those of the natural stone. As a result of the experiments, tension-compression diagrams for CAS and also the dependence of compliance from the relative length were obtained. Considering the substantial technological advantages of this composite, it is concluded that it is practical to use this material.
