This paper presents the results of a series of experiments on samples made of steel fibre reinforced concrete. The investigated samples were made with different concentrations of steel fibres ranging from 20.0 to 32.5 kg/m3. Twenty-one cubic samples (15 x 15 x 15 cm) and fourteen cuboid samples (15 x 15 x 60 cm) were used for this investigation. The article focusses on the effect of the concentration of steel fibres on the properties of industrial floors. For this purpose, both destructive and non-destructive methods were used and compared. As a result of this study, it has been proved that compressive and flexural tensile strength are lower with increasing air content and decreasing density of concrete. Moreover, it was found that there is a correlation between ultrasonic pulse velocity and rebound hammer results which together can be used to estimate the compressive strength of steel fibre reinforced concrete.
