【 摘 要 】

The paper deals with mechanical properties of high-strength concrete, which are illustrated in various laboratory tests. The aim of the paper is to compare the possibilities of concrete compressive and tensile strength assessment and modulus of elasticity assessment. Results of nine type laboratory tests are presented in summary. Tested material properties are complemented with testing of small structural element, the beam without shear reinforcement. The behaviour of structural element is analysed also with a non-linear numerical model that respects the quasi-brittle properties of the concrete, where fracture-plastic model for concrete is used.
