Originální abstrakt

The proportion of fibre reinforced concrete applications is increasing and testing methods for obtaining its exact properties are improving. Nevertheless, it is necessary to improve the knowledge of fibre concrete preparation, testing, and, above all, the statistical evaluation of test results, as there are still questions to which there are no known answers. This paper demonstrates the possibilities of statistical evaluation of crack mouth displacement (CMOD) tests performed on 24 specimens. Beams with dimensions of 150 × 150 × 550 mm were prepared from C25/30 grade concrete reinforced with two different types of steel fibres: 38 mm length and 52 mm length. It should be mentioned that longer fibres have lower tensile strength than shorter ones. Therefore, a statistical evaluation of the CMOD test results is presented.
