| Abstract: | The results of static and dynamic tests for three groups of ceramic materials based on zirconium dioxide ZrO2 and for zirconium dioxide concrete are reported. The static and dynamic tests were performed according to the conventional procedure and Kolsky procedure, respectively. The ceramic samples were obtained using different manufacturing technologies and had different initial densities and porosities. In the experiments, static and dynamic strain curves were obtained and strength characteristics were determined. The dynamic strength properties of ceramics and concrete are shown to depend on the stress growth rate. The dynamic curves of ceramics are compared with those of structural and zirconium dioxide concretes. |
